The thermostat controls the operation of a motorized valve which, during heating periods, opens when heat is required and which, during cooling periods, opens when cooling is required. The changeover from heating to cooling is achieved automatically by measuring the temperature of the ﬂ ow pipe. If the ﬂ ow temperature exceeds 30°C the thermostat operates as a heating thermostat, if the ﬂ ow temperature is less than 16°C the thermostat operates as a cooling thermostat Important note: It is essential that the circuit in which the pipe sensor is located is not closed off and that water circulates past the sensor at all times. This may require the ﬁ tting of a bypass valve between system ﬂ ow and return at the end of each circuit. Installation First remove the wallplate from the back of the unit. Ensure that there is a minimum of 50mm above the unit and 100mm below the unit in order to mount the plug-in module.

Fix at a height of approximately 1.5m from the ﬂ oor, away from draughts or heat sources such a fan-coil outlets, sunlight or ofﬁ ce equipment. Pipe sensor location Fix the pipe sensor to the ﬂ ow pipe using the clamping band supplied.Important note: It is essential that the circuit in which the pipe sensor is located is not closed off and that water circulates past the sensor at all times when the system is in operation. This may require the ﬁ tting of a bypass valve between system ﬂ ow and return to ensure circulation past the sensor.

Note: If HEAT/COOL/FAN outputs are 230V, link terminals L-COM7 GB - Installation Instructions Commissioning Prior to re-ﬁ tting the thermostat to the wallplate, the DIL switches on the rear of the unit must be set to the desired setting. DIL Switch options, shown in factory set position.

CHRONO 3CHRONO 68 DIL Switch descriptions Switch 4: If set to On/Off, both heating and cooling stages operate in on/off mode. If set to Chrono, heating stage operates in chrono-proportional modes, cooling continues in On/off mode Switch 3: Active only if switch 4 is set to Chrono. This switch determines the number of cycles per hour that the thermostat will impose on the system, the options are three 20 minute cycles or six 10 minute cycles Switch 2: Allows Celsius or Fahrenheit temperature scaling to be selected Switch 1: Not used in this model GB - Installation Instructions9 GB - Installation Instructions Mounting thermostat to the wallplate To mount the thermostat to the wallplate, align the tabs on the top of the thermostat with the apertures in the wallplate and hinge the thermostat down, pressing ﬁ rmly to engage the securing clip in the wallplate. Locking & limiting To lock or limit the setting range turn the setting dial to 3 and remove knob. Position the locking springs on the rear of the dial to the desired position and re-mount the knob ensuring that number 3 on the dial aligns with the reference mark on the case.10 Fan runs continuously Fan runs with heat or cool demand Thermostat off LED lit green when thermostat is powered LED lit orange when fan running LCD display shows actual room temperature unless knob is moved at which time a ﬂ ashing set temperature is momentarily displayed.
