Product Description
The HWP-FS (hot water) Series Programmable thermostat with Fan Only Switch is intended for use as a 2 circuit thermostat controlling a circuit pump and fan on a hydronic coil heating system, though it could be used when needing a 2 circuit control with 1 minute delay on the second circuit. This control solves the historic problem of using a standard 22 Amp bi-metal heating thermostat on a hydronic system which require high Amp loads to be accurate. Without a load they will not shut off properly, continuing to circulate hot water when not needed. This control positively controls both circuits creating energy savings and superior comfort control, while providing excellent hydronic control.
The HWP-FS includes a 7 independent day programming with 4 times and temperature settings per day to save energy and also start system before you get home. Also included is a Fan Only switch, allowing for fan only cooling operation in the summer months.
