Each day can be set with its own programme, or the programme can be copied to other days- so every day of the week can have the same programme- or you can have a different programme at weekends etc. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . We currently are able to accommodate the oldest and deprecated boilers to the very latest energy-efficient central heating systems. Easy replacement for the older versions of CM701 CMS701 CM707 CMS707 CM707A1029 CM907 CM901 CMS907 CMS907B1049 CMT901A1004 wired room thermostats.

With over 15 years’ experience of bathroom fitting, coupled with over 10 years plumbing retail experience we are confident we can meet the needs of the most demanding projects. I will also be installing Tado smart wireless radiator valves to 4 of the rooms which will have their own temperature control. For example, they mention it's great for setting differing temperatures, and it'll give you more accurate control over the house temperature. 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.

As per the image, my current thermostat has a brown wire connected to A (Live according to the sticker?

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'.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.

We also have a third on/off thermostat, one which works out how much the temperature will over shoot, and turns off before the target is reached, but does not use a mark/space ratio to adjust boiler output.
