About Our Product
The BH-1 Battery heater is designed to maintain the batteries in the Polaris
control box at a higher temperature when the system is installed in a
cold climate. The heater is easy to install and wire, and controlled by a
built in thermostat that activates the heater at temperatures below 40F
(4C). One or two heaters can be used depending on the number of
batteries installed in the control box.
Power for the heaters is supplied by the incoming 18VAC transformer up
to 200 feet from an AC power source. Single battery systems more than 200 feet and dual battery systems more than 300 feet from the AC power
source must be powered by a separate transformer. The heaters will not
work on solar powered applications.
