This Control Thermostat includes a Heater Contactor and is the replacement for the Hot Spring Classic model D spa prior to 1986. This kit is needed when replacing the thermostat (30203 ) due to the newer made thermostat’s inability to handle the required amperage of the Classic Model D.
Notes: The numbers on the control panel temperature dial do not correspond to any specific temperature. They are a convenient way to mark where a person likes the thermostat set.
Technical Specs.: 115 Volt AC
Warnings: Adjusting the “Allen” (hex) type screw on any thermostat part frequently causes the thermostat to fail.
