Programmable Thermostat type HWPRS
IntroductionIntroductionIntroduction
This thermostat can replace any standard room thermostat, and is designed for use with gas or oil heating systems. If you
wish to control electric heating note that the current rating is 3A resistive.
The thermostat is battery-powered and designed for wall mounting, using the backplate supplied. The HWPRS provides a
volt-free contact to switch any load up to 3A @ 230V 50Hz and can be positioned wherever you would normally fit a room
thermostat.
