Hi, As in header. I have an older gravity fed and pumped system. the present timer is a clunky type which we have to keep switching on manually as its knackered! Any ideas/recommendations for a good reliable programmer? tia. Stuart.
The Rolls-Royce of heating controls is the Honeywell CM927. It allows you to set different temperatures for different times of day and different days of the week. You can also tell it if you're going out a few hours and the house can be a bit cooler until you get back, or if you're away for a week so that you have frost protection while you're away but come back to a nice warm house. It's wireless so you can take the controller/thermostat into whichever room you happen to be in. Costs a hundred quid, mind.
I usually fit
the hot water - and Honeywell don't make a gold-plated Rolls-Royce model that does all that *and* the hot water.
this ones, always been good to me
But no boost button for the CH.
boost button on it, cant remember what it does :-)
Mine are the Horstmann programmer and thermostat:
(I'd make the programmer with pairs of change-over contacts per channel (for flexibility) rather than just a single CO contact - and I'd have the thermostat switchable to display "temperature now" rather than just the set-point - but that's all)

However, I cannot understand why the the tagret temp is not displayed on the main screen and requires a button to be pressed. Rather poor UI in my opinoin...
Without pressing any buttons it acts as a handy room thermometer to let you see what the temperature really is rather than what it ought to be.
My alarm clock displays in the corner of the screen (at all times) the times of the two alarms, saving me having to confirm them before I turn it to on. This is what I am/was after.
They do have an "Advance" button which moves the CH on to the next clock position.
But the one I bought, the buttons slowly got harder and harder to operate until it packed up altogether. Screwfix swapped it without a murmur. The replacement's been fine.
Get a Danfoss TP7000 which will do all of the same and also let you see both temps on the screen at the same time (or a clock, whichever you prefer).
I have a Danfoss TP9 which uses a remote temperature sensor.
The sensor replaced the previous room thermostat, using the same wiring.
I think that the modern replacement is the Danfoss 087N7892
I cant remember what I got, but its three separately timed zones. I use one for UFH, one for CH and one for DHW. boost, off completely and override on 24x7 each and every channel.
Newey and Eyre probably.
