1.6.b Operating Heat Pump (With an External Controller)
If the display indicates the unit is under remote
control, an external control device has been
configured to control the heat pump. See
external control device manual. Or contact
installer or manufacturer of that device.
PLEASE NOTE:
When using a SMART external control device, the time-out and service modes will
deactivate the Heat Pump.
1.6.c Operating Heat Pump (With an External Flow Switch)
When an external flow switch has been installed and enabled, the heat pump thermostat will automatically
switch between pool and spa depending on how the water flow actuators are set. The "Pool / Spa" button will
be disabled when this device is configured in the system.
Confirm with the installer if an external flow switch has been installed on the system.
1.6.d Operating Heat Pump (With a Gas Back Up)
If a gas backup heater is installed, it will be configured in one of two modes by the installer (Scheduled mode
or 24 hour mode). This affects how the heater operates.
PLEASE NOTE -
Gas backup modes are only available when the ambient air temperature is below 60° F.
See "Using Gas Boost" on page 20 for exception.
