Combi boiler in a flat with just a room stat in the lounge (from what
I can see).

Can you get (at a reasonable cost) a simple Clock / timer stat for
such circumstances and if so, would / could they be battery powered,
assuming the stat isn't currently fed by mains?

I think Adam was trying to be funny. I put HW/CH in the title because
the boiler does both so I threw that in *in case* there was some
special reason there wasn't a timer for the CH already.

Like a fridge needing the heat of an incandescent lamp or a boiler
coming on on it's own to prevent freezing etc.

Modern boilers will have a frost stat internally but if yours doesn't you can check the instructions for that prog stat to see if it does.

Excellent, thanks very much for that mate. It seems to tick all the

I think it would be used in the 5+2 day mode as one occupant has the

Having a look though the instructions I'm not sure if this unit is as
'flexible' as I might have hoped, or maybe it is but I just wasn't
expecting it to work this way ...

"10.
Programming Time/Temperature Periods
Note:
•
There are no OFF periods with this controller. As soon as a Start time
begins, heat will be demanded until the temperature reaches/falls to
the selected set point, then it will move on to the next Start
time/temperature period, and so on. The closest you can get to turning
the TRT035N programmable thermostat OFF, will be to set the selected
period(s) to 10°C, this way the heating will not turn ON unless the
temperature drops below these set points.
•
If you do not want a higher temperature period in the middle off the
day, adjust the temperature for this period downward, to match those
of the proceeding and subsequent period temperatures."

Anyone care to put that into user friendly terms please?

Like, I would have thought you could set the on / off times and the
temperatures for each time. That you could also override it (either
way) at any time, or tweak the temp and it would revert back to the
pre-programmed routine at the next time interval?

Maybe that's what it can do but the translation makes it sound more
complicated?

It's never off, just think of it as a frost-stat at all times when you
don't set higher required temperatures ...

e.g set 20 for 7am to get up, then 15 for 9am after you leave the house,
18 for 5pm when you return and 10 from 10pm for overnight, then you can
boost it by the odd degree or two for the odd hour or two as required.

You can set the temperature as low as 10 degrees. That's "off" for most

that."


I've installed a few similar for people who've had no trouble in

installing heating systems (or indeed lecturing on neuroscience).

Id seriously consider a Hive (or similar) system. You can then set things
to a profile which matches your needs and, best of all, turn it on/off
remotely via your phone etc.

If, for example, we go out for the day we can turn off the heating and turn
it on remotely when we are heading back. When we are returning from trips (
holidays) I turn on the hot water ( and heating if needed) so we can have a
shower etc.

You can set it up for anti-frost etc. , to automatically detect when
everyone has left the house ( using their phones), when someone is
returning, .....

You can add individual radiator valves to control each room - electronic
thermostatic valves with a remote override.

Even, should you like gadgets, control the temperature via Alexa etc with
your voice.

The most boring instructional video I've seen in a long time.

No off periods but you could set every other start temperature to, say,
5 C which will effectively turn the CH off unless the pipes are about to
freeze.

An any modern electronic room stat provides timing. My controller box is
configured to be on for CH 100% of the time and my room stat provides
the timing with 4 off configurable on/off periods each with its own
temperature for both on and off.

While mine is a wireless module with the receiver fitted to the location
of my old "simple" thermostat the mains switching is achieved by use of
a relay. I assume any battery run thermostat will have a relay for any
mains voltage switching.

Better, they have a latching relay. So power is only drawn from the
battery when turning the relay on or off. No power is needed to hold the
relay in either state.

Not always. Many modern ones are volt free contacts so there is no connection between the relay contacts and the internal gubbins, which are battery powered.

Means there is no requirement for a neutral at the stat location, just L and Call.

Most of these electronic room thermostats cater for a variety of
different configurations so may use battery for electronics and a
mechanical relay for switching.

I'm sure there are mains powered programmable stats. I've never seen one
yet, they all had 1 or 2 AA cells to power the stat electronics and a
latching relay.

The ones that use a rotary encoder instead of up/down buttons are
more intuitive to use. The set-point and the current room
temperature should be displayed simultaneously.
