Default
0 setting not available if the system type
(ISU 2000) is set to Heat Pump
Maximum of 2 Heat Stages for conventional
systems.
Maximum of 1 Backup Heat Stages for heat
pump applications. Note: this is not
counting the compressor heat stages on
heat pump systems.
This ISU is only displayed if ISU 2010 is set
for Electric Forced Air or Hot Water Fan Coil.
The thermostat automatically energizes the
fan in heat when running a heat pump.
The thermostat automatically allows the
system to run the fan in heat when set for
gas or oil forced air systems. For radiant
systems (excluding hot water fan coil) the
thermostat does not energize fan in heat.
Only displayed if the system type (ISU 2000)
is set to Heat Pump) and Backup heat stages
(ISU 2071) is set to 1. Change to Aux and E
Independent only when you have separate
wires to Aux and E terminals on UWP and
want the AUX wire energized with heat pump
as backup heat and E energized separate of
heat pump when switched to em heat mode.
Only displayed if the system type (ISU 2000)
is set to Heat Pump) and Backup heat stages
(ISU 2071) is set to 1.
Only displayed if the Aux/E terminal control
(ISU 2175) is set to "Aux and E Independent".
Not displayed if equipment type (ISU 2000)
is set to cool only or cool stages (ISU 2070)
is set to 0.
This ISU is only displayed when ISU 2000
System Type is Heat Pump and ISU 2180
Backup Heat Type is Standard Efficiency
Gas Forced Air or High Efficiency Gas Forced
Air.
Not displayed if equipment type (ISU 2000)
is set to cool only or cool stages (ISU 2070)
is set to 0.
Differential is the minimum number of
degrees rise or fall required during off cycle
to switch from the last active mode (heat or
cool) to the opposite mode when the
thermostat is in auto-changeover.
Differential is NOT deadband. See Auto
Changeover operation on page 37.
