HydroHeat Supplies have always offered zone control relay boxes, this example is for a 13 zone system being installed in Tasmania. We only use off the shelf components so parts can be replaced in the future. Our system offers 24 Volt thermostat control and 240V actuator output. The zone control system can be configured to suit your design.
