Frequently Asked Questions - P5603R Emos

How to install the P5603R thermostat?

Before installation, cut off the power supply to the heating or cooling system. Fix the back cover to the wall using the provided screws and wall plugs, then connect the wires to the NO, NC, and COM terminals according to your installation diagram. Reattach the front part after inserting the batteries.

What batteries to use and how to change them?

Use two 1.5 V AA (LR6) alkaline batteries. Do not use 1.2 V rechargeable batteries. To change the batteries, remove the front part of the thermostat and replace the batteries respecting polarity.

What to do if the screen remains blank?

First check the battery polarity, their charge status (not flat), and good contact. If nothing appears, remove the batteries and reinsert them to reset the thermostat. Ensure the batteries are new and alkaline.

How to set the temperature?

Turn the adjustment knob to the right to increase the temperature, to the left to decrease it. The set temperature displays for 5 seconds, then the screen returns to room temperature.

What is CHRONO mode (TPI)?

CHRONO mode (or TPI) is an algorithm that learns the thermal behavior of the room to anticipate needs. It allows more efficient heat management by adapting heating cycles. Activate it via the DIP switch (ON position on switch 2).

How to set the number of cycles per hour?

On the DIP switch, switch 3 allows choosing between 6 cycles/hour (OFF) and 3 cycles/hour (ON). 3 cycles is recommended for underfloor heating or heat pump; 6 cycles for a gas boiler or zone valve.

Can I use this thermostat for air conditioning?

Yes, the thermostat supports cooling mode. Set the DIP switch: switch 1 to ON to activate cooling (and deactivate heating). The phase cable must then be connected to the NC terminal instead of NO.

What does the flat battery icon on the screen mean?

The flat battery icon indicates that the batteries are low and must be replaced. Use new 1.5 V AA alkaline batteries.

Where to install the thermostat for optimal operation?

Install the thermostat on an interior wall, about 1.5 m from the floor, away from direct sunlight, drafts (windows, doors) and heat sources (radiators, TV, refrigerator). Incorrect placement can affect temperature measurements.

How to clean the thermostat?

Use a soft slightly damp cloth to clean the device. Never use solvents, abrasive products or excess water. Do not immerse the thermostat in water or any other liquid.

INSTALLATION

Attention:

Before changing the thermostat, disconnect the heating/air-conditioning system from the mains power in your flat. This will prevent potential injury by electric current.

Read the thermostat manual carefully before using the device for the first time.

Turn off power supply before installing the thermostat!

Follow applicable standards during installation.

Placement of the Thermostat

The placement of the thermostat significantly affects its functioning. Choose a location where family members spend most of their time,

preferably on the inside wall where air circulates freely, with no direct sunlight. Do not place the thermostat

in the vicinity of heat sources (such as TV sets, radiators, fridges), or close to a door (due to frequent shocks or vibrations). If you do not follow these recommendations, the thermostat will not maintain room temperature correctly.

Installation of the Thermostat

The rear cover of the thermostat has 6 pre-made openings for mounting onto a wall.

Remove the rear cover and use the enclosed screws and wall plugs to mount the thermostat to a wall.

The connection terminals are protected by a plastic cover, see Fig. 3.

Connect the wires leading out of the junction box to the marked terminals on the thermostat in accordance with the wiring diagram.

Putting the Device into Operation

1. Remove the back portion of the thermostat and insert 2× 1.5 V AA batteries. Only use 1.5 V alkaline batteries; do not use rechargeable 1.2 V batteries.

2. Replace the back of the thermostat.

3. The thermostat now has an active screen and is operational.

If the thermostat is not working properly, please check the polarity of the batteries and whether they are sufficiently charged, or reset the thermostat by removing and reinserting the batteries.

If it appears on the screen, replace the batteries in the thermostat.

Setting Temperature

To increase temperature, turn the wheel right.

To reduce temperature, turn the wheel left.

The set temperature will be shown on the screen for 5 seconds, then the room temperature will be shown instead.

Choosing Operating Mode

Unscrew the rear cover of the thermostat.

There is a DIP switch on the back of the thermostat which is used to set the following functions.

Available Functions in HEATING Mode

cooling mode off 1 ON heating mode on
CHRONO mode off 2 CHRONO mode on
6 cycles/h 3 3 cycles/h
°F unit of temperature 4 °C unit of temperature

CHRONO (TPI) Mode

CHRONO mode, also known as TPI (Time Proportional and Integral) is an algorithm that has a simple memory capable of „learning“ how to reach and maintain room temperature. It has a basic calculating capability: It uses collected data and current temperatures and predicts how long heat needs to be generated (the boiler must remain on). It is a type of intelligent control, since heat delivery lasts until the desired value is reached, then the boiler is turned off to improve energy efficiency.

The mode runs in cycles, with their length measured as number of cycles per hour. During normal use, it is difficult to notice the difference in the way the heating system runs. However, it is noticeable that the thermostat runs for a shorter period of time when room temperature starts approaching the set temperature. Once the set temperature is reached, the operating cycles become shorter to maintain the temperature. TPI calculates the speed at which the room loses heat and prevents the room from getting colder by activating heating as needed.

Setting CHRONO (TPI) Cycles

In heating mode, the CHRONO function can be set to 3 or 6 cycles per hour.

3 cycles are recommended for controlling underfloor heating or controlling a heat pump.

6 cycles are recommended for controlling a gas boiler or a zone valve.

Temperature Differential Setting

If you turn off the CHRONO function, the thermostat will activate/deactivate based on the temperature differential.

The temperature differential (hysteresis) is the difference in temperature required for switching the system on and off.

The differential value is 0.4 °C.

If, for example, you set the temperature in heating mode to 20 °C , the thermostat activates heating as soon as room temperature drops to 19.6 °C and switches heating off when temperature reaches 20.4 °C .

Available Functions in COOLING Mode \*

cooling mode on 1 ON heating mode off
delay off 2 delay on
4 minute delay 3 2 minute delay
°F unit of temperature 4 °C unit of temp

Delay prevents the thermostat from switching because of short-term temperature changes – protects the boiler from frequently activating and deactivating.

Upkeep and Maintenance
