Product overview

The thermostat is designed for use in systems equipped

with fan coils served by a 2-pipe central changeover system.

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 ow

pipe. If the ow temperature exceeds 30°C the thermostat

operates as a heating thermostat, if the 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 tting of a bypass valve between system ow and

return at the end of each circuit.

Installation

o First remove the wallplate from the back of the unit.

o Ensure that there is a minimum of 50mm above the

unit and 100mm below the unit in order to mount the

plug-in module.

!

o Fix at a height of approximately 1.5m from the oor,

away from draughts or heat sources such a fan-coil

outlets, sunlight or ofce equipment.

Pipe sensor location

o Fix the pipe sensor to the 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 tting of a

bypass valve between system ow and return to ensure

circulation past the sensor.

Commissioning

Prior to re-tting the thermostat to the wallplate, the DIL

switches on the rear of the unit must be set to the desired

setting.

DIL Switch descriptions

Switch 4: If set to On/Off, both heating and cooling operates

in on/off mode. If set to Chrono, both heating and

cooling operates in chrono-proportional 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.

Mounting thermostat to the wallplate

o 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

rmly to engage the securing clip in the wallplate.

Locking & limiting

o To lock or limit the setting range turn the setting dial to 3

and remove knob.

o 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.
