A range of basic electro-mechanical time controls for

heating and domestic hot water systems, widely

favoured for their simplicity of operation. They have

been particularly popular for Local Authority

specification.

All models feature a 24-hour clock with colour coded

On and Off tappets, which are simply moved to the

desired time settings on the dial to provide up to 2 on

and 2 off periods per day.

The control module plugs in to a separate wallplate/

terminal block making installation and servicing as

simple as possible.

Factory Replacement Units

Plug-in modules are available for each model in the

Mark 3 range, including some units not in current

production. By removing the outer case and the two

screws holding the module to the wall mounting-plate,

the whole module assembly can be unplugged without

any disturbance to the electrical wiring, and the

replacement module simply plugged in.
