INTRODUCTION

This thermostat can replace most common
residential thermostats and is designed to be used
with electric, gas or oil heating control systems or
cooling systems.

Unlike conventional thermostat devices, this control
is a new type of thermostat which separates the
functions into two units. The Receiver serves for
wiring connections and heat/cool on/off control The
Transmitter serves as the user interface and for
temperature sensing / control. the two units are
linked by radio frequency (RF)

The advantage is that the user can keep the
Transmitter nearby and can read / control the
temperature of the living area in immediate use.

Transmitter layout:

Neutral

Live output
