I am working towards replacing my current thermostats with Omnistat2 units. I have a three zone baseboard hot water boiler as well as a separate single stage a/c unit. Both units use millivolt thermostats. I've determined I can use the RC-1000's but will need to add a 24VAC transformer to power each thermostat. In addition, I will need an HAI 29A00-1, Thermostat Isolation Module, for my main thermostat that operates the a/c and well as one heat zone. So far, so good (I think). 8)
Now my questions:
1 - Spec calls for a 24VAC 5-20VA transformer. Can I use a 24VAC 40VA transformer safely?
2 - Can I use one transformer to provide power to all the thermostats?
Thanks for the help!
