4. Heat, Cool and Auto Modes Operation -
Certain heat pump models have the ability to both
heat and cool.
a. These heat pumps can be setup to operate in any one of three modes:
•
Heat only mode
•
Cool only mode
•
Automatic Heat and Cool – The heat pump automatically switches between heat
and cool based on whether the water temperature is below or above the active
setpoint.
b. If the cooling option is available, the operating modes can be changed as described here.
Press the MENU SELECT button repeatedly until the Heat or Cool screen is displayed.
Once displayed, press the up or down arrows to scroll through the heat, cool and auto
options. The last option shown on the display will become active.
5. Relay Remote
– In relay remote operation the heat pump is started and stopped by remote
relays which are connected to the remote POOL, COMMON and SPA quick connect connectors
on the back of the control board. When conductivity is provided between the pool and common
connections or the spa and common connections the heat pump will start as long as the water
temperature is not over the local set point (under for chiller operation). The local set points are
active in relay remote operation.
a. If the heat pump is to be controlled by a remote device such as an automation system, the
heat pump set point should be made higher (if heating) than the desired temperature. For
example, if your remote connections wired to the back of the board are connected to the
pool and common terminal, and you want your pool maintained at 85 degrees, you should
set the heat pump to 90 Fahrenheit and then turn on the remote function.
b. If you have a separate spa, you must have the automation system wired to the spa and
common terminals on the back of the board. If you want your spa temperature maintained
at 102 Fahrenheit, you should set the heat pump to 104 Fahrenheit and then turn on the
remote function.
c. To activate the relay Remote Mode, press the MENU SELECT button repeatedly until
the Relay Remote screen is displayed. Once displayed, press the UP or DOWN arrows
to go between ON and OFF. The last option shown on the display will become active.
