1.6.a Operating Heat Pump with a Call Flex
When a Call Flex has been installed and configured for a heat pump, the circulation pump will respond to
commands from the heat pump. Confirm with the installer if a Call Flex accessory has been installed on the
system. See "
Call Flex Accessory (# 0030-LEDS) " on page 40.
l
If installed, the operator has the option of changing how this accessory works using either "CALL" mode,
"FLEX" mode, or "OFF" (Default).
Using Call Mode:
When the accessory is in CALL (or override) mode, the circulation pump will be set to periodically
activate. This allows the heat pump to sample the water temperature.
l
The default is 2 hours between each activation.
l
The water temperature will be sampled for 30 seconds.
l
If the water temperature has fallen below the set temperature, the circulation pump will allow the heat pump
to operate until the set temperature is reached.
