INTRODUCTION
A programmable thermostat is a device that combines the functions of both a room thermostat and
heating controller into a single unit. The programmable thermostat is used to switch the heating system
by means of time and temperature change. This unit is not like a standard programmer. It works by
controlling the temperature according to a series of programmed settings that take effect at different
times of the day.
The ST620ROF from Salus Controls is a stylish and accurate 5/2 or 7 day programmable electronic
thermostat with a large, easy to read Liquid Crystal Display (LCD). This programmable thermostat has been
specifically designed to be used Volt Free. Unlike ordinary single unit design programmable thermostats,
this is a new type of unit that separates the operational functions into two units.
The Receiver is used for wiring connections and heat on/off control. The ST620 provides the user interface
and temperature sensing / control. The two units are linked together by a Radio Frequency (RF) signal.
The use of the revolutionary Touch Ring technology makes for simple usage, and is coupled with a unique,
smart design. The LCD display will show the current room temperature and the 'one touch' operation makes
the ST620ROF easy to operate.
