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 oor, away
from draughts or heat
sources such a fan-coil
outlets, sunlight or of ce
equipment.

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 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
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.
