A range of basic electro-mechanical time controls for heating and domestic hot water systems favoured by Local Authorities nationwide for simplicity of operation.
The control modules plug into a separate wallplate/terminal block making installation and servicing as simple as possible. Please note this unit is for replacement purposes only (no backplate included)
All models feature a 24-hour clock with colour coded On and Off tappets which are simply moved to the desired position on the dial to provide 2 on and 2 off periods per day.
Can be used to replace the Randall 3033 with only a minor wiring change on the backplate.
