1.7.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 53.
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.
Using Flex Mode:
When the accessory is in FLEX (or extend) mode, the heat pump will start to heat if the set temperature is
lower than the water temperature and the heat pump has water flow.
The circulation pump does not
automatically activate in this mode .
l
If the desired water temperature has not been met by the end of the circulation pump's schedule, the normal
"time-off" setting will be overridden.
l
The circulation pump will continue to operate until the set temperature has been met.
l
The circulation pump will then deactivate until the next normally scheduled start time.
