Here's the deal: I have 3 pieces of 220v elec. baseboard heat, 2000w ea, on individual circuits. the homeowner wanted to control all by the use of a single thermostat. I proposed using resistive load contactors (SqD). I have a 2 pole & a 4 pole, each with 24v coils. the thermostat is a Honeywell T87F Heat only, run with a 24v 40VA transformer.

I believe the transformer isn't capable of pulling in both coils at the same time, also the heat anticipator on the thermo may be smoked.

The question:
If I upgrade to a 100va transformer & get a new thermo, will the system function?
or is the low voltage line current too much for the T87 ???
Should I switch to a different single contact thermo?

Thanks
