Backlight Display with On/Of Illumination switch, also System off switch

Star Hydronic Performer: Backlight Display with On/Of Illumination switch, also System off switch.

The HWP (hot water) Series was intended to be used as a 2 circuit thermostat controlling a circulation pump and a fan on a hydronic coil heating system, though it could have other uses where you need a 2 circuit control with a 1 minute delay on the 2nd circuit.
This control will solve the historic problem of using a standard 22 Amp electronic heating thermostat on a hydronic system. They require high amp loads to be accurate. Without a load they will not shut off the circulating hot water when not needed.
This control positively controls both circuits creating energy savings and superior control.

INSTALLATION

This line voltage device should be installed and serviced by a qualifi ed electrician. The thermostat has been designed to mount to a standard 2″ X 4″ electrical outlet box. Leveling of the thermostat is not required. Mounting screws are provided. Mount the thermostat about fi ve feet above the fl oor in an area with good air circulation. Avoid mounting the thermostat where it will be affected by drafts, air from ducts, and radiant heat sources such as appliances, the sun, or plumbing pipes in the wall.
