Hi

I have a Heatline S30 Compact boiler and would like to install a
wireless thermostat.
The ones I have seen so far are CM61 RF or Towerstat RF.

The CM61 RF seems easier to install as it has two outputs (volt free
contact) to the boiler and I have two contact (low voltage) available.
The only thing is it has only 6 switching options so you can program
three sections of heating per day.

The Towerstat however looks like it can do more than 6 per day but only
in 1 hour slots. Also it has only three terminals. Live, Nuetral and
Output. Live and neutral is easy but what about Output, my boiler has
two connections which to connect it to? Also does anybody know for sure
if you can program more than 6 switchings per day on the towerstat, the
manual doesnt seem to clarify.

Thanks

PS btw I have no TRV's on the any of my Rads

No, six. For each time point you program in a new target
temperature which will be maintained until the next time point
(unless overridden). If you want the heating to be off completely
for one or more time periods you just set the desired temperature
to a very low number. If you just want to think in terms of on or
off, then yes you are limited to 3 on periods, but mine at home
drops to 11C during the day and then picks up in two steps in the
evening - much more flexible than a programmer+stat setup.

The CM67RF is a better buy than the CM61 as you can have different
programs for each (e.g. for weekends or because you get home early
on Friday)

Any ideas on the Towerstat?

Thanks

No, after I fitted my first CM67 I lost interest in everything
else g. If you take time to understand the various options (like
using the party button to kill the heating for a couple of hours
when you go out) it is a brilliant piece of kit.

The CM60-series has been superceded by the CM900-series now.

Appears functionally the same however a bit more 'flash' (and
user-friendly with the on-screen prompts).

P.S. Note however that it has optimisation turned off *by default*
which is sure to go unnoticed by some.
