USE WITH ASTRALPOOL GAS HEATERS
Gas heaters (and electric heat pumps) generally rely on a water pressure switch to activate the heater control circuit. When
a variable speed pump operates on low speed the water pressure produced in generally insufficient to activate the pressure
switch and control circuit within the heater.
If using a compatible AstralPool Gas Heater you can automatically increase the speed of your Viron XT pump to ensure the
water pressure switch is activated and the heater obtains enough water flow to operate correctly.
A RJ12 (6 wire flat cable) specifically wired and obtained from AstralPool will connect your pump and heater. Refer to
Heater Instruction Manual for data cable connection details.
