Load compensation
The Comfort I and II RF thermostats are able to have an
intelligent conversation with the boiler. This enables a
load compensation function that is capable of delivering
up to 3% savings, based on measurements documented
in the ErP Directive (Energy-related Products Directive).
Load compensation works by comparing the actual
temperature and the set-point temperature and adjusting
fl ow temperature accordingly to maintain a low return water
temperature for maximum condensing.
The Comfort I RF twin channel model is an intelligent programmer that plugs into the boiler and is supplied with a separate
room thermostat for adjustment of room set-points temperature.
Extremely reliable RF signal
Using the latest RF (radio frequency) technologies for
maximum reliability, the Comfort I provides wireless
communication between the boiler room thermostat
transmitter. It includes a radio signal strength indicator
menu to assist in fi nding the best location for the
room thermostat.
Holiday mode
The system can very simply be set to holiday mode, during
which time the heating system provides frost protection
only, while the hot water is switched off.
Landlord function
A ‘landlord function’ for enabling a maintenance/
annual service date to be set is also available for
social housing customers.
*Comfort I RF is a +3% control when used with a Greenstar gas-fired boiler and a +1% control when connected to a Greenstar Heatslave II oil-fired boiler.
