Q: I need to replace a Randal 30 33 with the 40 33. It says there is a minor wiring change to the back plate. Is these easy for someone with some electrical experience to do thuis and what does it involve

A: It is simple moving cables from one terminal to another and placing a link. It's quite easy to do. Full details are supplied with the unit.
Q: How do you take off the old 4033 unit and replace with a new unit. I cannot see any screws to undo, ie where is the connection to the backplate located.

A: You will need to unscrew the rings around the switches. Then the front cover will come off and the rest of the unit will slide up off of the backplate.
Q: My heating is coming on at the same time as the water, only my heating is in the off position....what could be causing this?

A: This is usually caused by a faulty motorised valves.
Q: My Randall 4033s' clock appears not to be working. It is silent and the dial does not rotate but when the switches are put into the ON position everything works. Can I just replace the clock or will it be the whole unit? Thanks.

A: I'm afraid you will need to replace the whole programmer.
Q: I have a Randall 4033 It has been installed for many years. The heating only comes on when I put the water on also. Will replacing it solve the problem

A: This is more likely to be a motorised valve problem than a programmer problem.

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.
