T7200/T7300 THERMOSTAT OPERATION

STARTUP

When power is first applied, an internal startup program begins. This takes place after any total loss of power (supply voltage and backup battery) and lasts 2 seconds.

At this time, default temperature setpoint values are used for temperature control. These are: heating 68 F [20 C] and cooling 78 F [26 C]. Following the startup period, you can enter new setpoints which will be used in place of these default values.

Should a power failure occur after your time and temperature schedule entries are made, the backup battery will maintain your schedule up to 60 hours. As long as either system or battery backup power is present, your program is available and will be used for temperature control.

OPERATION

SELECTING THE DESIRED OPERATING DISPLAY

The DISPLAY key allows you to select a continuous display of time or temperature. Each press of the DISPLAY key will toggle the display between time or temperature.

INDICATORS

No Program in Thermostat Memory

A display of 4 dashes (----) indicates that there is no program stored in the thermostat's memory. This will occur when power is first applied to the thermostat, or when power was lost to the thermostat while battery backup was either weak or not installed.

Loss of External Power

A blank display indicates loss of external power. The backup battery will maintain your time and temperature schedule during power loss. The keyboard and display are inoperative while the thermostat is operating on battery power.

BATT Displayed on LCD

BATT displayed on LCD indicates backup battery is weak or not installed. Refer to section titled BATTERY ACCESS AND REPLACEMENT for instructions.

Temperature Display of --°

A display of 2 dashes and a degree symbol ( --^ ) indicates a temperature sensor failure. See section titled TROUBLESHOOTING GUIDE for instructions.

MINIMUM OPERATION TIMES

The T7200 and T7300 thermostats incorporate minimum operation times of 2 to 4 minutes. These times are in effect after startup, anytime power to the thermostat is removed and then reapplied, or after heating or cooling goes either on or off. These time delays will protect and extend the life of your heating and cooling equipment.

Due to these times, the thermostats will not react instantaneously to setpoint changes.

T7200/T7300 THERMOSTAT OPERATION

PROGRAM SCHEDULE

Each day of the week can be individually programmed with 2 Occupied and 2 Unoccupied periods to make maximum use of schedule variations.

Occupied operation is based on Occupied Heat and Occupied Cool setpoints. Unoccupied operation is based on Unoccupied Heat and Unoccupied Cool setpoints.

Intelligent Recovery™, based on a setpoint ramping feature, is used when switching from Unoccupied operation to Occupied operation. This selects the optimum time to begin building warmup or cool-down, and can vary depending on space temperature deviation from setpoint. The end result of Intelligent Recovery™ is the correct temperature at the occupancy time. This increases energy savings while also providing increased user convenience.

SECURITY AND OVERRIDES

SECURITY

The T7200/T7300 thermostats provide program security capability which, if used, can lock out programming. This prevents tampering with thermostat setpoints and schedules. If the lock out function is not used, the thermostat can be programmed normally as described in this manual. When the thermostat is locked out, only limited keyboard functions are available. The three overrides, setting clock times and program reviews can be performed when the keyboard is locked out.

OVERRIDING THE THERMOSTAT'S PROGRAM

The security feature of this thermostat does not lock out the use of the 3 overrides.

Two of the overrides (3 Hour Occupied and Setpoint Adjust) are timed for 3 hours, at which time the thermostat returns to the normal program. The last override (Continuous Unoccupied) is not timed. Once this override is in operation, it cannot be exited unless the CONT UNOC key is pressed or another override is placed into operation.

None of these 3 overrides may be used at the same time, and the last override placed into operation will be in control.

SECURITY AND OVERRIDES

KEY USED FOR THE 3 HOUR OCCUPIED OVERRIDE

3 HOUR OCCUPIED

This override is useful in situations where people will have to be in a building when it is normally vacant such as after normal working hours or on weekends or holidays. Press the 3 HOUR OCCUPIED key to place the thermostat into the Occupied mode,

controlling the space temperature to the occupied setpoints for 3 hours. The indicator on the left side of the display will point to 3 HR OCCUPIED while this override is in effect.

SECURITY AND OVERRIDES

KEYS USED FOR THE SETPOINT ADJUST OVERRIDE

SETPOINT ADJUST

This override is useful in situations where the occupied space feels too cool or warm for the occupants and a temporary change of setpoint would make the temperature more comfortable. It can be called from either the Occupied or Unoccupied modes and functions in this way:

— Press the 3 HOUR OCCUPIED key. If in Unoccupied, the thermostat will go to the Occupied mode, controlling the space temperature to the Occupied setpoints for 3 hours. If in Occupied mode, no change of setpoints will occur. However, this will ensure 3 hours of Occupied setpoint control regardless of any Unoccupied Start Times that may be programmed. The indicator on the left side of the display will point to 3 HR OCCUPIED while this override is in effect.

THEN: — Press the the + key. This will adjust the setpoint up by a preprogrammed "Amount of Setpoint Adjust". As an example, Occupied Heat is set for 70 F and "Amount of Setpoint Adjust" is set for 5 F. After the + key is pressed, the Occupied Heat setpoint will be 70 + 5 or 75 F. The thermostat will then control the space temperature to 75 F and the indicator on the left side of the display will continue to point to 3 HR OCCUPIED during the remainder of the 3 hours of adjusted setpoint.

OR — Press the - key. This will adjust the setpoint down by a preprogrammed "Amount of Setpoint Adjust". As an example, Occupied Heat is set for 70 F and "Amount of Setpoint Adjust" is set for 5 F. After the - key is pressed, the Occupied Heat setpoint will be 70 - 5 or 65 F. The thermostat will then control the space temperature to 65 F and the indicator on the left side of the display will continue to point to 3 HR OCCUPIED during the remainder of the 3 hours of adjusted setpoint.

NOTE: Refer to the section titled TO SET THE AMOUNT OF SET- POINT ADJUST for instructions on how to vary the setpoint adjust.

SECURITY AND OVERRIDES

KEY USED FOR CONTINUOUS UNOCCUPIED OVERRIDE

CONTINUOUS UNOCCUPIED

This override is useful in situations where the building will be vacant for an extended period of time (such as temporary closings or long holidays). Pressing the CONT UNOC key will place the T7300 into the unoccupied period for an indefinite time.

When in this mode, the thermostat will control to the unoccupied setpoints with the indicator pointing to CONT UNOC. A second press of the CONT UNOC key will cancel this override mode and return the T7300 to normal operation.

SAMPLE SCHEDULE 1

In this sample schedule, the owner wants the building's temperature to be at the OCCUPIED HEAT/COOL setpoint beginning at 7:00 a.m. on Monday through Saturday.

The building's UNOCCUPIED times vary. On Monday, Tuesday, Thursday, and Friday, the building is UNOCCUPIED beginning at 5:00 p.m. The UNOCCUPIED Period starts later on Wednesday (9:00 p.m.), and earlier on Saturday (11:00 a.m.).

On Sunday, the building is unoccupied all day. Neither an OCCUPIED period nor an UNOCCUPIED period starts on Sunday. The building is UNOCCUPIED starting at 11:00 a.m. on Saturday, and remains UNOCCUPIED until Monday morning at 7:00 a.m.

In programming Sunday's schedule, the CLEAR START TIME key would be used to clear OCCUPIED START and UNOCCUPIED START times for Sunday.

Note that start times for Tuesday, Thursday, and Friday are identical to those for Monday. Each day can be programmed separately. Optionally, Monday's start times can be entered, then the Monday schedule copied into each of the other 3 days with the aid of the COPY DAY key.

PROGRAMMING THE THERMOSTAT

SAMPLE SCHEDULE 2

In this sample schedule, the owner wants the building's temperature at the OCCUPIED HEAT/COOL setpoints twice a day Monday through Friday, and most of the day Saturday. On Sunday the building will be unoccupied all day.

Monday through Friday's first OCCUPIED period will be from 9:00 a.m. to 2:00 p.m. The second OCCUPIED period will be from 4:00 p.m. to 1:00 a.m. the following morning. Care must be taken when entering the second UNOCCUPIED START time for these days. The second UNOCCUPIED START time will actually occur on the following day because the thermostat changes days at midnight (12:00 a.m.). Therefore the second UNOCCUPIED START time of 1:00 a.m. is entered into the following day (Monday will not have a 1:00 a.m. UNOCCUPIED START time, Tuesday through Saturday will).

Saturday's OCCUPIED period is 10:00 a.m. to 2:00 a.m. the following morning. Saturday's UNOCCUPIED START time, for the same reason as above, actually occurs on Sunday. Therefore the 2:00 a.m. UNOCCUPIED START time is entered into Sunday.

No other building occupancies are planned until Monday at 9:00 a.m., so no other START times need to be entered into the thermostat.

The COPY key may be used to copy Tuesday's program to Wednesday through Friday.

BATTERY ACCESS AND REPLACEMENT

1. Do not disconnect the power supply to the system during battery replacement. This would cause backup battery operation and battery drain until the system is powered up.
2. Loosen Allen screw at each corner along the bottom of thermostat.

3. Remove thermostat by swinging bottom away and upward from wallplate or subbase. Do not detach cables.

4. If battery replacement is required, replace only with a fresh Mallory MN1604 or equivalent 9-volt alkaline battery.

5. Locate the battery holder on the back of the thermostat. Snap a 9V alkaline battery into the connector/holder observing polarity. Slide the battery up to the battery connector until connected.
6. Reattach T7200/T7300 to wallplate or subbase and secure by tightening both Allen screws along bottom of thermostat. Do not overtighten.

STEP 1 - KEEP THERMOSTAT'S CABLES CONNECTED TO SUBBASE OR WALLPLATE.

STEP 2 - SNAP BATTERY IN PLACE.

STEP 3 - SLIDE BATTERY UP TO THE BATTERY CONNECTOR UNTIL CONNECTED.

IMPORTANT

Do not connect battery until the thermostat's cables are connected and the HVAC system is ready to be put into operation. Battery power will be drained if system power is off for lengthy periods.

GLOSSARY

Backup Battery — A battery located in the T7200/T7300 thermostat that provides electricity to maintain your time and temperature schedule during power loss. If the battery is dead or runs down during a power failure, the time and temperature schedule will be lost. However, the thermostat will control to a standard set of "default" setpoints when power is restored.

Default Setpoints — Temperature settings of 68 F for heating and 78 F for cooling that are built into the T7200/T7300. These assure that the system will remain operational even if the thermostat is not programmed or the time and temperature schedules are lost due to battery failure.

Economizer — An auxiliary control system which allows use of cool outdoor air for free cooling, in place of electrical air conditioning equipment. Based on the availability of outdoor air for "free" cooling, the economizer control system will provide cool air, increasing comfort without the extra expense of running mechanical cooling. Only if outdoor air cannot or does not sufficiently cool the space will mechanical cooling be allowed to run.

"Free" Cooling — See Economizer.

Intelligent Recovery™ — A control method which adjusts the heating warmup and cooldown time periods based on outside weather conditions. Commonly referred to as “optimized start.”

Mechanical Cooling — Cooling that is provided by running compressors to extract heat from the conditioned space.

Minimum Operation Times — Fixed minimum on/off equipment run times used to prevent harmful short cycling (turning on and off too often) which can significantly reduce equipment life or cause permanent damage.

Occupied Temperature Setpoint — The heating and cooling temperature settings used when the room or building is scheduled to be occupied.

Occupied Start Time — The selected time at which the air conditioned space is to reach the comfort temperature for people occupying the room.

Setpoint — The selected temperature at which the heating/cooling system is to maintain the conditioned space. There are separate setpoints for heating and cooling in the OCCUPIED and UNOCCUPIED time periods.

GLOSSARY

Single Zone Air Conditioning System — A packaged system that includes heating, cooling, and air distribution equipment. It might also include an economizer (see Economizer). These systems are self-contained, often roof mounted, and condition the air in a specific local area with its own thermostat. Larger buildings may have 2 or more areas or zones, each with its own air conditioning system and thermostat.

Thermostat Cycle — The time necessary for the heating or cooling equipment to come on, operate, and turn and remain off until the next time it is needed. Cycle time is controlled by the thermostat. For example, mechanical cooling equipment might turn on and then go off 4 times in an hour.

Unoccupied Temperature Setpoint — The heating and cooling temperature settings used when the room or building is scheduled to be unoccupied.

Unoccupied Start Time — The selected time at which the air conditioned space is allowed to become cooler/warmer to save energy. NOTE: can be temporarily overridden by using the "3-Hour Override" key.

7-Day Program — Each day of the week (7 days) may be individually scheduled for occupied or unoccupied start times. This allows maximum flexibility for building scheduling.
