Active call for cooling only
–
Dehumidifier can operate only during an active call for cooling.
Dehumidifier control options are accessed by navigating to
Installer Setup > Accessories Settings
.
Note:
Pivot thermostat has an onboard humidity sensor which can be enabled through
Installer Setup

.
Dual Fuel Operations (Heat Pump with Aux Indoor Heat)
The Pivot thermostat can control a dual fuel system without the need of an external dual fuel kit.
Important:
An outdoor temperature sensor must be installed and enabled for restricted modes to be
available.
Dual fuel operations
:
•
Non-restricted mode (Thermostat uses non-restricted mode when you have heat pump with aux
heat, but no outdoor air sensor)
–
The unit determines which heat mode operates to maintain comfort based on the calculated
system load value. With a load value in compressor heating range, the heat pump operates and
if the load value raises to auxiliary heat range, the heat pump cycles Off and the auxiliary heat
source cycles On. Once the load value falls below the auxiliary heat range, the auxiliary heat
cycles Off and the heat pump cycles back On.
•
Restricted mode (only compressor heat — Thermostat has ODT and lockouts setup)
–
When restricted mode is enabled, an outdoor temperature lockout can be set to disable
compressor heating operation. When the outdoor temperature falls below the compressor heat
lockout, the system only operates on auxiliary heat source. At any temperature above the
compressor heat lockout, the system operates the same as non-restricted mode, heat pump, or
auxiliary heat that are allowed based on system load value. When the compressor heat is locked
out, the outdoor temperature must rise at least 4°F above the compressor heat lockout setting
above, allowing compressor heat again. Refer to the illustration below.
•
Restricted mode (compressor and auxiliary heat — Thermostat has ODT and lockouts setup)
–
When the outdoor temperature is above the auxiliary heat lockout, only compressor heat is
allowed.
–
When the outdoor temperature falls below the compressor heat lockout, only auxiliary heat is
allowed.
–
When the outdoor temperature is between the compressor heat lockout and auxiliary heat
lockout, the system operates the same as non-restricted mode, heat pump, or auxiliary heat is
allowed based on system load value.
There is a 10°F minimum deadband between the compressor heat lockout and auxiliary heat
lockout. Once the compressor heat or auxiliary heat is locked out, the outdoor temperature
must rise or fall at least 4°F above or below the lock setting before allowing compressor or
auxiliary heat again. Refer to the following illustration.
