heat and cool.

a. These heat pumps can be setup to operate in any one of three modes:

• Heat only mode

and cool based on whether the water temperature is below or above the active
setpoint.

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

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 SP A 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 temperaturemaintained
at 102 Fahrenheit, you should set the heat pump to 104 Fahrenheit and then turn on the
remote function.

c. T o 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.
