110 V Tstats

in THE MAIN WALL
Have a house w/2 line voltage non-programmable tstats (White-Rodgers 1A10-651) for a boiler & would like to go programmable - I am a renter & only have a $100 leeway from my landlady. What do you all recommend ???

Probably don't need 7 days & will install them myself, as I have worked as an electrician work in the past. The house is a leaker, so maybe go to just one zone ??? Plus the boiler has a coil & can't keep up w/the mornings' call for heat & hot water.

But, what can we do as renters !!!!

Thanks

    Maybe a set of these? 120 volt, an A model for air temp, 7 day programmable. Get a pair, save the old ones & reinstall them when you move out.

    Exactly what I was thinking.
    Line voltage is unusual for hydronics. Is it controlling a fan coil?

    Zman - There are 2 circs (1st & 2nd floors) from the Peerless boiler.

    Ratio - yr suggestion is not for this application !!!

    Unless you have the 4 wires shown, the Aube stat will not work. It needs 120 volts for its brains, and then switches a separate 120 signal for the load. $100 is a tight limitation. Guessing that you only have 2 wires behind the stat. If so, one option would be to use a battery powered programmable low voltage t stat, and then set a transformer relay downstairs at the pump, using the two wires as the switch leg for the transformer relay package.

    Relay in a Box makes a single unit that has the relay, transformer and all built into a small package, but again, $100 is a tight budget.

    Here is an Aube (Honeywell) that should work: TH140-28-01. Honeywell describes it as "well suited for hot water heating".

    Uses batteries for stat electronics. Wire with 120V diagram. You can get two for under $100 at Supplyhouse.com.

    Most all of the electric radiant floor heating brands offer line voltage stats from mild to wild.

    I really wish they did make a fan center but , sadly , they do not.
