How to install & wire Nest thermostat for dual / multi zone system with radiators and UFH

#nest #nestdualzone #ufh

In this video I show you how to wire and install and wire Nest thermostats on a multi zone / dual zoneheating system that has both: under floor heating and radiators. In this Nest thermostat installation guide we have two heating zones. Each zone is controlled by one Nest thermostat. First zone has wet under floor heating and second zone has radiators. Wet under floor heating does not have actuators as it is only a single zone set up, and I am using a single 2 port zone valve to control UFH and fire the boiler. Under floor heating pump is fired by a call for heat from the heat link and also connected to a brown wire from the zone valve.
