Honeywell T6373, T6372 User Manual
XE70 SERIES T6372/T6373
PRODUCT SPECIFICATION SHEET
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.
FEATURES
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
Slide switches allow manual control of system
operation and fan speed
Auto heat/cool changeover possible (on some
versions) by using pipe thermostat
Optional extras:
- range stops F42006646-001 (20 per pack, enough for
10 thermostats)
