Controls up to 4 zones
Our receiver has 4 built-in zones, namely 3 heating zones + 1 hot water zone. Each heating zone requires an independent thermostat control, so 1 receiver can pair with up to 3 thermostats.
1 heating zone with/without hot water zone → 1~2 zone
2 heating zone with/without hot water zone → 3 zone
3 heating zone with/without hot water zone → 4 zone
