Battery Powered Room Thermostat

The RET B is a battery powered room thermostat

that combines the beneﬁts of a conventional

analogue setting knob and an LCD display to

show temperature and thermostat status.

Styled on the RMT and RET thermostat

range, the RET B provides accurate electronic

temperature control without the need for an

external power supply. This makes it an ideal

solution for system upgrades when replacing

conventional electro-mechanical two-wire

thermostats.

The RET B utilizes a micro-processor which, in

addition to providing accurate temperature

control, also drives a small LCD display. During

normal operation, this LCD displays actual room

temperature and changes momentarily to show

set temperature whenever the setting dial is

moved. The LCD is also used to display output

relay state and to indicate when the batteries

require changing.

The micro-processor also provides other

added features not normally found in such

thermostats. These features include:

Selection of either on/oﬀ or chrono-•

proportional control

Cycle rate adjustment if chrono-•

proportional control is selected

Selection of heating or cooling control•

Selection of compressor delay timer if•

cooling operation is selected

Selection of Fahrenheit or Centigrade•

scaling

The range comprises of three models:

RET B

Basic thermostat with analogue setting and LCD

display.

RET B-LS

Thermostat with analogue setting and LCD

display, plus a manual Auto-Oﬀ switch to turn

the thermostat output oﬀ during periods when

it’s operation is not required. When set to Oﬀ

the LCD clearly shows that the thermostat has

been turned oﬀ.

RET B-NSB

Thermostat with analogue setting and LCD

display, plus a manual Day/Night switch

which, when set to Day position, controls

at the temperature set on the dial. When

Night is selected, the thermostat controls

at a temperature 7°F lower than the set

temperature.
