HVAC Scheme

Control4 climate control solution relied on CCZ-T1-W wireless thermostat and was limited to the limitations of it which is basically heat pumps, radiant heating systems etc. This solution is unfortunately not adequate especially for HVAC system controls. With this HVAC system solution driver set you will be able to control most of the HVAC devices available on market.

Using the CoolMaster or PI485 gateway you may control multiple indoor units, even using CCZ-T1-W, and by connecting it through Ethernet you may do multi controller installations like hotels and apartment buildings. This driver set is able to control the under floor heating in conjunction with the HVAC unit or in standalone mode.
