PRODUCT SPECIFICATION SHEET |
|
|
The T6376 and T6377 are designed to control the valves, |
|
|
|
|
|
the fan and the compressor in split units, heatpumps and |
|
|
small air conditioners. |
|
|
The thermostat operates the compressor to provide either |
|
|
heating or cooling (as selected by the system switch) 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 switch which gives the 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, or a HEAT/OFF/COOL |
|
|
switch |
|
|
Heat/cool changeover operation can be accomplished either |
|
|
by a manually operated HEAT/FAN/ COOL switch or a |
|
|
HEAT/OFF/ COOL switch on the front of the thermostat. |
