Honeywell 7 Day Programmable Thermostat CM707

Product Information

However with a gas modulating boiler this is counter productive, as every time the boiler is switched off by the thermostat any heat in boiler is lost out of the flue, and on switching on again it does so at full output, so the boiler never gets time to modulate and the mark/space switching does seem to work, but causes the boiler to work inefficiently.

Controlling the climate in your home is not an easy task and the Honeywell CM707 CM700 Series thermostat will do just that. It can also be set to 'manual', where it acts as a simple digital thermostat without any timer features, or 'off' where the heating will only come on if the ambient temperature falls to 5°C to prevent freezing. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . Some boilers like Bosch have not adopted OpenTherm, they have their own modulating thermostats, but these only work in one room, so unless open plan home not really very good control, it would seem the Hive system was designed to get around this problem when boiler manufacturers only allow on/off electrical control. The CM700 range of programmable room thermostats are designed for social housing provider and specifier market needs by providing automatic time and temperature control of domestic heating premises.It likely will need re-wiring, as the Honeywell CM707 thermostat is on/off, Nest e can be used on/off, but that would be a bit counter productive when boiler is OpenTherm and thermostat is also OpenTherm. The optimising setting means that you do not have to guess how long it takes to heat up the house/room - well not much anyway. This is used, for example, if the 'stat is locaqted in a poor place that might suffer from draughts - since the 'stat will be senseing air that is colder than in the rest of the room, this control will allow you to alter the displayed temp to represent the main room as opposed to the 'draught'.

I want to replace the thermostat with a Nest Thermostat e which I bought, but I'm struggling with the wiring. The better your problem and question is described, the easier it is for other Honeywell owners to provide you with a good answer. It is compatible with a wide range of heating systems, including combi boilers, and can be wired or used wirelessly with an RF module. But you also say "New Build" it is required to have zones in new builds, all that is required is TRV heads, but often one finds zone valves, but the Nest system does not seem to be designed to work with zones, EPH do an OpenTherm thermostat which can be set as Master/Slave but I know of no others, often the zone valves need removing to fit the likes of EvoHome or Wiser.Bought as a direct replacement for an obsolete one that wasn’t working properly, as suggested by our heating engineer - works straight out of the box and easier to programme than our last one - should have replaced it she’s ago! There is a wired thermostat in the front entrance room that controls all the hallways and the downstairs rooms and another wired thermostat in one of the bedrooms which controls all the upstairs rooms and bathrooms. I note it does have a 'Temp Offset' feature that can change the displayed temp in relation to the room temp. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.

something needs to be done with the 2 switch valves in the airing cupboard that control the flow to the each radiator zones. So with a gas boiler the TRV head is king, this is the device used to control room temperature, and because it gradually opens and closes it works in harmony with the boiler, allowing it to modulate as it is designed to do.

If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. To further improve the ease of use and assist installation, the CM700 range includes a large LCD display. e. the entire home temperature controlled by the new Tado wireless smart thermostat which will be placed in the living room). They say it is a great product that allows them to set differing temperatures during the day and on different days. The thermostat only switches on when, for example, the difference deviates more than 2˚C from the set room temperature.The CM700 range of programmable room thermostats is designed for social housing provider and specifier market needs by providing automatic time and temperature control of domestic heating premises.
