Mechanical Timer, 24 Hour
The easy to use, 24 hour mechanical timer is a simple plug-in option. Continuous, timed or off modes can be set using the tappets which provide 15 minute period operation. An integral clock provides the time of day. ErP Class 0, no additional efficiency.
RF Electronic Programmable Thermostat, 7 Day
This wireless Radio Frequency (RF) digital timer provides heating and hot water control and features a simple user interface, room temperature control, +Hours mode and Holiday mode. It features English language boiler fault messages with suggested corrective actions and a timed pre-heat to save energy and reduce costs. Summer/winter time (GMT/BST) is automatically updated, and the boiler output is modulated by a 7 day timed control of central heating by Opentherm, saving energy and costs. Logic+ Combi only: If it is required to limit radiator surface temperatures under all conditions, use the RF Mechanical Programmable Room thermostat kit. ErP Class 5, 3% additional efficiency.
Weather compensation can be achieved when the boiler is fitted with an optional outdoor sensor. Weather compensation works by measuring the temperature outside the home and adjusting the temperature (or flow) of the radiators inside. If the weather is particularly cold outside, the outdoor sensor will communicate with the boiler intelligently to increase the temperature inside. This process also works in reverse, as the outdoor temperature increases, the flow to the radiators too will decrease. This process allows the system to operate more efficiently by preventing spikes in heating activity. ErP Class 2, 2% additional efficiency.
