Dual Setpoints
(for use in
Auto
mode only): When using dual
setpoints, separate heat and cool setpoints are used. When the
ambient temperature drops below the heat setpoint, the controlled
zone will call for heat to maintain the heat setpoint. When the
ambient temperature rises above the heat setpoint, the controlled
zone will not call for cooling until the temperature exceeds the cool
setpoint. When the ambient temperature drops below the cool
setpoint, the controlled zone will not call for heating until the
temperature is below the heat setpoint.
NOTE:
When dual setpoints are used, the P-TSTATRF in the
controlled zone will display the setpoint closest to the ambient
temperature.
For instructions on setting the system mode, refer to “Set the System Mode”
on page 58.
To set the temperature:
•
Single Setpoint:
Touch
k
or
j
to raise or lower the temperature setting.
NOTE:
When using a single setpoint, there is a 20-minute change
limiter to prevent system toggling.
•
Dual Setpoints:
1. Verify that the controlled zone is set to the
Auto
mode.
2. To lower the heating or cooling setpoint, touch the
j
button
under the setting to be changed. To raise the heating or
cooling setpoint, touch the
k
button under the setting to be
changed.
Set the System Mode
A Prodigy-controlled HVAC zone has up to five operating modes:
NOTE:
Not all modes are available for all HVAC zones.
•
OFF
: In
Off
mode, all HVAC systems are disabled.
•
HEAT
: In
Heat
mode, the thermostat uses the heating system to
maintain the setpoint temperature. On the P-TSTATRF, a “flame”
icon will be displayed.
•
AUXILIARY (AUX) HEAT MODE
: In
Auxiliary Heat
mode, the
thermostat uses only the auxiliary heat output on heat pump or dual-
fuel systems (if equipped) to maintain the setpoint temperature. This
setting can be useful when the heat pump is being serviced or when
there is an unexpected problem with it. On the P-TSTATRF, the
display will flash the “flame” icon when the system is in
Auxiliary
Heat
mode.
•
COOL
: In
Cool
mode, the thermostat uses the cooling system to
maintain the setpoint temperature. On the P-TSTATRF, the
“snowflake” icon will be displayed.
