FAN-COIL THERMOSTATS

2-PIPE FAN-COIL CONTROL

PRODUCT DATA

The T6372 and T6373 are designed to control the valve, or
the valve and the fan in 2-pipe fan-coil applications.

The thermostat operates an on/off valve to provide control at
the desired setpoint temperature.

The fan can also be controlled from the thermostat. In some
cases it is wired to run continuously, and can be switched off
with the system ON/OFF switch, while with other models
there is a choice of running the fan continuously, or cycling it
with the thermostat.

Versions are available with a manual 3-speed fan switch, and
with a system on-off switch.

Heat/cool changeover operation is also possible on some
versions. This function can be accomplished either by a
manually operated heat/ cool switch on the front of the
thermostat or in some versions automatically by the use of a
pipe thermostat on the supply water pipe of the fan-coil.

• • Dual diaphragm sensing element ensures close

temperature control for all loads and applications

• • Attractive modern styling makes this thermostat ideal

for locating in the occupied space, particularly in
offices or hotels

• • All versions have heat anticipator, which improves

temperature control in both heating and cooling
operation

• • Thermostat mounts directly onto a wall or conduit

box

operation and fan speed

• • Auto heat/cool changeover possible (on some

versions) by using pipe thermostat

• • Optional extras:

- range stops

- tamperproof cover
