Compatibility with multi-zone forced hot water boiler

[jdotson56]

The compatibility checker says my forced hot water boiler system is compatible, but I want to know if a Nest Power Connector is required since I don't have a c-wire. Simple wiring is:

1. RC-RH jumper

2. RH connected to system

3. W connected to system

Red and White wires are the only wires going to the system.

 Also, is the Nest Learning Thermostat required of is this Nest compatible as well: https://store.google.com/us/product/nest_thermostat?hl=en-US

Hi jdotson56,

Thanks for posting! I'm glad to help you with this compatibility check.  If the compatibility checker says your system is compatible, you likely won't need a C-wire or Nest Power Connector. However, using one is always recommended because it provides consistent power to your thermostat. You can try using it without the C-WIRE, but if your thermostat loses power, you'll need to install it then.

Regards,

Axel.
