I have a boiler controlled by a 4 zone taco relay box. Zones are 1st fl, 2nd fl, basement and domestic hot. I have been home sick this week and its been cold out so i have been able to observe the boiler working under its hardest conditions.
I am constantly hearing the boiler fire for one the zones shut and then only a few minutes later have to fire for a another of the zones. This is a single stage 85% efficient boiler.
I am thinking on days like this week when people are home all day it may make sense to have the boiler operate all of the zones off of one thermostat.
My plan is as follows:
Splice the neutrals for all of the thermostats together.
Take the hot from the main 1st floor thermostat and take 3 pigtails off of it.
The first pig tail will re attach to the hot size of the 1st floor relay box.
The second pig tail will hit a switch then a diode (to prevent back feeding the first floor zone when we want more heat in the 2nd floor) then splice it into the hot coming from the basement thermostat and head for the relay box.
The third pig tail will hit a switch then a diode (to prevent back feeding the first floor zone when we want more heat in the basement) then splice it into the hot coming from the 2nd floor thermostat and head for the relay box. .
My questions are as follows:
1) Will this work to achieve my heating control desired?
2) What size diode do i need? I will probably use a led so it can double as an indicator light.
3) Any idea if this will improve efficiency? I am thinking that at times like when we are on vacation during the winter it deff will.
TIA
