Cool Control Specifies the HVAC control of this thermostat. This parameter
describes the thermostat’s capability to control a heat pump
system. The thermostat can also be disabled from controlling a
cooling system and instead operate as a heat-only thermostat.
Disable – Specifies that there is no cooling system present.
(Heat only thermostat.)
1C – Enables the heat pump as a standard single stage
cooling system.
2C – Enables the heat pump as a standard dual stage cooling
system. There are two separate compressor wires from the
heat pump connected to the thermostat.
Second Stage Offset Specifies a secondary source of cool air outside the heat pump
system, for example, electric baseboard or a gas furnace.
This parameter is only enabled when 2C Cool Control is
enabled, otherwise it is disabled.
+0, +2, +3, +4, +5, +6°F

Stage Delays
Compressor Delay Specify the minimum time (in minutes) between successive
heating, cooling or heat to cool and cool to heat cycles in heat
pump applications. This parameter ensures a safe heat pump
compressor delay or off time guaranteed between cycles. This
parameter may also be used in fuel burner mode, whereby this
parameter ensures a safe A/C compressor delay or off time
guaranteed between A/C cycles.
0 – Enables the cooling system to cycle immediately upon
completion of the previous cycle. This is a diagnostic
feature and should not be left in this state or compressor
short cycling and subsequent damage may occur to the
compressor.
3 through 10 – Time in minutes required between the
completion of a cooling cycle and the next subsequent
cooling cycle. The default delay is 3 minutes.
Interstage Delay
Specifies the delay between the 1
st
stage activation and 2
nd
stage
activation.
0, 15, 30, 45, 60, 90 - Time in minutes
Aux Heat Delay Specifies the delay between the active heat pump cycle (either
single or dual stage) and activation of the Auxiliary Heat source.
Note: In a dual stage heat pump, Aux Heat is available only after
the 2nd stage is active.
