A range of general purpose timeswitches which provide a single output circuit. The range includes a simple 24 hour electromechanical model, plus two electronic models which offer Weekday/Weekend or 24 hour operation and 7 day or Weekday/Weekend operation.

All three units fit the well known GP wallplate and have an identical wiring configuration. Systems may be upgraded without the need for rewiring.

Question

Hello – I have a Danfoss 103 central heating timer and a Danfoss re230p thermostat that is in my hallway. Could you recommend a wireless central heating controller that I can move to different rooms in the house, many thanks.

Answer

Thank you for your enquiry - If you wish to change to a wireless programmable thermostat system then
please find product page link for the Honeywell CM927 Wireless Thermostat Set
https://www.uk-plumbing.com/honeywell-cm927-7-day-wireless-programmable-room-thermostat-p-41212.html
which comes complete with both the Thermostat and Receiver and is by far our most popular unit.

Question

Hi – I have been renovating my kitchen and over a month ago I removed a Danfoss Randall 24 Hour Time switch 103 Electro-Mechanical from the wall which was broken and not working. I need a like for like replacement and was wondering which time switch would be the best option from a wiring point of view. It is a cistern system I have and my previous switch was only ever used for a timer and a on/off switch, it didn’t switch the immersion heat on/off as there is a separate switch up stairs for that. I would be grateful if you could advise me on what I should do and what switch I should purchase.
