About this deal

The programmer is suitable for surface or switch box mounting and comes complete with a built-in battery back-up. When I examined the old control unit, I noticed the battery inside was dead and leaking so badly that the connection to the circuit board had corroded and loosen off.

From the product page you can use Paypal Express Checkout which will take you straight to your Paypal account where you can login to complete payment or apply for Paypal Credit.it fitted the hole perfect, was exactly the right make and fit and works brilliant plus it looked very smart.

The thermostat cable will be between terminal 4 on new programmer and brown of CH two port valve, connect brown of the CH valve directly to terminal 4 so it excludes the now redundant thermostat cable. The HONEYWELL ST699B1002 ELECTRONIC PROGRAMMER 230V - Now Use 4201085 is a genuine, brand new Honeywell Heating Supplies product, covered by a Honeywell Heating Supplies manufacturer's guarantee. Bought this as a replacement for the same unit which had burned out (I suspect following a number of power cuts in the area). The ST electronic dual zone timer is used to control gravity,primary or fully pumped central heating systems requiring a single 24 hour programme with two ON/OFF periods per day.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. As I had not checked the part when it was delivered I was expecting a lot of hassle to get it changed. I'll go take a pic The two cables entering from the RHS are room stat wires - obviously no three core available so a pair of 1. The front control unit has spring loaded contacts to the base plate, so you don't even need to do any rewiring.

It will fit into the same backplate and is easy to programme with a slider switch, which includes plus and minus buttons.If you are unsure on the parts we have a technical team which can assist you at any time during the working day.

Alternatively if you view your parcel once items have been added and enter your postcode you will see what derlivery services are available. It controls the timing of the hot water and central heating twice a day, but the best bit is that anybody can set the times without having to read any complex instructions! Just looking for something as low cost as possible that I can control via the internet connection if I'm away from the home. Item arrived all packaged intact and unopened part for an old boiler will be recommending and using this site again. This is currently controlling a Honeywell S plan system - CH and DHW (and has done for ages) with absolutely no probs on a Worcester system oil boiler.If approved and you accept, you'll have a credit limit added to your PayPal account ready to use immediately.
