3060
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.
