Product overview

The thermostat is primarily designed for use in systems

equipped with 4-pipe fan-coil units. It may also be used in

other heat / cool systems, including split systems and air to

air heat-pumps.

The thermostat controls room temperature by sequencing

the operation of heating and cooling. A selectable dead-band

prevents overlap of heating and cooling processes. For

systems equipped with compressor derived cooling, including

heat-pumps, a selectable compressor delay timer is also

included. If used to control a heat-pump, the reversing valve

can be energisation on either a heat or cool demand.

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.

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 descriptions

Switch 8: 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

GB - Installation Instructions

Switch 7: Active only if switch 8 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 6: Allows Celsius or Fahrenheit temperature scaling

to be selected

Switch 5: Enables or disables a compressor delay timer

which is activated at the end of each cooling call.

This feature need only be used where cooling is

provided by a compressor as opposed to chilled

water. Set to Cmp del if a compressor delay is

required, otherwise leave set to No Cmp del

Switch 4: Active only if switch 5 is set to Cmp del. The op-

tions are 3 or 4 minutes

Switch 3: Allows dead-band between heating and cooling to

be set, options are 2°C or 4°C

Switch 2: Allows application to set as fan coil or as heat

pump. If heat-pump is selected, the output

normally used to operate the heating valve is

re-assigned to the heat-pump reversing valve,

the compressor stop/start signal for both heat

and cool calls is re-assigned to the relay normally

used to operate the cooling valve

Switch 1: The function of this switch is dependent upon the

setting of switch 2:

 Switch 2 set to Fan-coil: Leave set to TS2

 Switch 2 set to Heat-pump: allows the reversing valve to

be set up to be energised in heating mode (R+), or

energised in cooling mode (R-)

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.
