Cooling with 3-Stage Reheat and 10 Degree Night Setback/Setup
This configuration is the same as on the previous
page except for the simple addition of a SPST relay
or switch and a resistor (see chart below for value).
The switch or relay is driven by a night setback/
setup signal from other equipment not shown. When
the contact is closed (e.g., by a timer), the added
fixed resistance of, for example, 41.2K ohms between
thermostat terminals A and 12V would indicate
that the room is approximately 10° F warmer than
it really is. This would inhibit the heat stages from
coming on during the unoccupied mode (night
setback). If the resistor and switch are instead
connected between thermostat terminals A and –,
the room would seem 10° cooler than it really is,
inhibiting cooling during unoccupied times.
NOTE: This configuration requires the system fan
to be on during setback/setup mode.
