Hello all,
I have a 4 zone relay box controlling my boiler. It is controlled via 3 thermostats 1 per floor plus one for the domestic hot water tank.
I want to tie all three heating zones together such that when the first floor thermostat calls for heat it will make all the zones fire. To do this i can simply run a jumper from one to each other on the low voltage side of the relay box. I am doing this to keep the boiler from short cycling and it makes the house more comfortable and i think may save energy.
The problem is that occasionally I want extra heat in the basement or second floor. If I have those thermostats call for heat they will make the first floor zone also turn on by the current going in the opposite direction on the jumper wire.
I know very little about electronics. I want to know what kind and size of diode i should use. The circuit is 24v .18amps.
Cliff Notes:
I need a diode to stop .18 amps at 24volts.
Also if I am way off base and none of this will work let me know
Thanks,
Mark
