Boiler Coordinator
Doing Off Peak? or any kind of dual fuel? Then you'll want to add the Boiler Coordinator. It automates switching between a main boiler and a backup boiler when the electric utility provides an “off-peak” signal. This little circuit board replaces several rib relay connections to coordinate the use of 2 boilers for any reason (it doesn't just have to be off peak).
The Off Peak Boiler Coordinator circuit board adds right on the HUG Hydronics In-floor Heating Control Board between pumps sections 8 & 9. Takes just minutes to install with standard tools, One more way HUG Hydronics is making in-floor heating simple.
Will be installed before shipping.
