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.

Best price and brilliant service
Had what I wanted (many places didn't) at a very good price and delivered when they said. Can't say fairer than that. Will use again.
Having made an error in what I thought I required HCO were very helpfull in pointing me to what I actually needed and then to take the wrong items back and refunding me with the amount I paid for them. All done very quickly with emails being answered by return.
