Thermostat

A friend has a system that has a thermostat for the a/c system and one for the oil fired boiler. Will one digital thermostat control both of the systems.

[CincyHVAC]

Yes, if a professional does the installation.

[HVAClambright]

yes they should. Doesnt the newer thermostats come with a Y1, Y2 and W1, W2? for heating and cooling?

[woodsman]

Depends.

That's a 2 stage stat.

Seperate transformers for ac and heat?

You can get a single tstat to run both just need more info.

Here is more info, First off I am just want make sure who she calls to do the job says and does this the right way. There are two White Rodgers analog thermostats now. One for the A/c and one for the oil-fired boiler. I will check about the transformers.

it will work, its how my home is done. consult a local pro so it gets wired correctly, otherwise things go poof!

If there are 2 tstats you most likely have 2 seperate control circuits hense 2 transformers.

If there using 1 it must be one hell of a huge VA transformer to be powering up the ac and bolier.

Do some reasearch and do it right the first time buddy.

the hardest part might be physicaly getting the wires all to one spot. and 'stat location does matter. the final price might be a bit of a shock
