The HW Non Prog. Electronic Thermostat
The HW (hot water) Series was 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 Programmable Electronic Thermostat
Adds 7 independent day programming with 4 times and temperature settings per day to save energy and also start system before
you get home.
The HWPT Programmable Electronic Thermostat
Programmable features plus it adds a 15 minute pump exersizer every 24 hours as required by code on potable water heating
systems. First cycle will start in 12 hours from the power on time so that all cycling will happen at night.
