Programmer vs Programmable Thermostat.

[skyhawker]

I am sure this must have been covered but I cannot seem to find.

We are having a 2 zone heating installed.

What are the pros/cons of the following setups and what would you go for?
1. A programmer and 2 simple thermostats or
2. A programmer plus 2 programmable thermostats or
3. No programmer for heating and just 2 programmable thermostats.

We want to use Honeywell so will be getting the 2 channel programmer and both heating zones will be on the same timer. Difference in the zones will be controlled by thermostat.

Option 3.

No point thinking about the others.

Are you sure you understand the difference in operation between the items.

Programmer controls on/off of heating by time and thermostat by temperature? and programmable thermostat does both?

Yes, but the Honeywell (as well as other lesser units) will predict the start and stop times based on your requirements.


Depending on your boiler and general setup there are even better ways of doing it.

We have a Valiant ecotec plus 637. S plus system.

What is the better way?

The Honeywell programmer or thermostat?

Shame about the boiler.

But.... single channel programmer for the hot water and either CM927, CM907 stats for the heating.


If you want to be funky - Honeywell Evohome can do everything and have internet control.

Thanks for this.

This is a poor boiler?

Could be worse .


If it was a superior type you could have had room level modulating.


The other alternative is Vaillant's own controls, btu they are terribly designed for the end user.

IF we would go with option 2 and we were to install a timer for the heating and also 2 programmable thermostats, could they work together, or is there something inherently bad with a timer on the system?

I am thinking that if the thermostats were to pack in or if we find that they play up for whatever reason we would still have the timer as a backup control.

So on a 'normal day' the timer would be set to on all day and the thermostats would be doing the on/off switching, and if there is ever an issue with something intefering with the termostats we could revert to the programmer.

It would be pointless.
