FR110 Programmable Room Thermostat

Six heating and hot water set-points

The controller provides the choice of six weekly heating

programmes, with six switching points per day. When

used with system boilers it also offers a weekly hot water

programme with six switching points per day. On combi

boilers the six switching points can be used to switch

pre-heat on where the hot water will be delivered to the

tap quickly, and energy saving economy mode where the

pre-heat function is turned off.

Pre-set heating programmes

The FR110 offers three pre-set temperature proﬁ les for

added convenience.

•

Comfort setting (21ºC), typically for use in the morning

and evening

•

Economy setting (15ºC), typically used to keep the

building warm through the day

•

Frost protection (5ºC), for when the property is

unoccupied for long periods or the heating is off in

cold weather.

Battery back-up

Use of a low voltage supply from the mains, rather than

relying on battery power, provides a clearer display for the

user and ensures they don’t have to worry about replacing

batteries. For extra peace of mind, the controller is supplied

with a battery that will provide up to six hours back-up.

Load compensation

Once installed, the FR110’s integral low voltage EMS Bus

device communicates with the boiler’s built-in Heatronic

3 controls to provide load-compensated control that ﬁ nely

tunes ﬂ ow water temperatures to heating demand.

The resultant reduced boiler cycling and the fact that the

boiler remains warm rather than frequently cooling down

and heating up again provides energy savings compared to

older style controllers.

Integrated solar heating control

The FR110 can also be used in conjunction with Worcester’s

ISM1 Intelligent Solar Module (see page 22) to optimise use

of renewable solar energy for water heating.
