Wireless Thermostat & Biasi combi wiring

[the_jinj]

Hi

I have a Biasi M90E 28S combi boiler which I am going to add a controller to. I was initially looking at the Draytech 111 or 711 which offer the volts free timeswitch I need, however I noticed the Horstmann HRFS1 wireless thermostat which also allows programming (www.screwfix.com/p/horstmann-hrfs1-room-thermostat/93829)
A look at the installation guide (http://www.horstmann.co.uk/downloads/ElectronicDocuments/ThermoStats/RF%20Programmable%20Room%20Thermostat.pdf) seems to suggest that it could be used volt free so would offer a better solution than just the 711 and no room thermostat etc....

Would this be ok to use or am I missing something?

Cheers
Neil

Depends what you want to do. The Draytons will provide timed on and off periods for your ch. It will be wired to your boiler.

If you want the same thing, but with the addition of being able to control temperature, the Horstmann is what you need - it's a programmable, wireless room thermostat.

All your choices are suitable for your boiler, as they all provide volt-free contacts/switching.

I was going along the lines of using a thermostat as it might save money in the long term.....never had one before, is it a worthwhile extra to have for this reason or should I just stick to the plain controller?

Cheers

Always a good idea to have a room stat, as it will turn boiler off when temp up to what you need. Will save money.

Wherever you fit the stat, if the rads in that area have thermostatic valves, you will need to leave them on max. Otherwise, the valves and stat will conflict with each other.

Cheers again!

Going to give the HRFS1 a bash, cheap enough off of eBay

A good investment. Should pay for itself in gas savings.
