4.6 Optional Installation
4.6.a Pool and Spa Combination Heating
The heat pump is equipped with two thermostats; one for pool and one for spa. The water is maintained at
the selected thermostat set-point depending on the selected thermostat. Please note
– when heating the
spa, the water must be isolated from the pool by selecting the correct water isolation valve position.
Pool / spa installations can be automated with an
“External Flow Switch”. This option changes the selector
thermostat each time the pool or spa isolation valve is positioned. See “Available Accessories” on page 35
for more information.
4.6.b Spa Setback Heating Option
When using a heat pump to heat a spa only (without a pool in the water circuit), the “POOL” thermostat
can be used as a setback control. Set t he “SPA” thermostat for the desired spa temperature. Select the
“POOL” thermostat and set it at a point 10-15º F below the desired spa temperature. This allows the spa to
be held at a heated temperature
using the “POOL” thermostat, but somewhat lower than normal spa-use
temperatures.
When ready to heat the spa, select the “SPA” thermostat to heat the spa to the desired temperature. This
will result in reduced warm up periods over full cold starts.
Switch back to the “POOL” thermostat when
done using the spa.
To prevent excessive heat loss and increased run time, use a spa cover and turn off air blowers when
heating spas.
