Electronic thermostat H128

digitalsmartprogrammable

Description
Wireless control system for hydraulic underfloor heating based on the H128 series. The H128-CC kit includes the wireless central unit and a WiFi gateway for local and remote control via app (iOS/Android). The H128-T thermostat is programmable and additional H128-T units can be added to control multiple rooms/zones.

Wireless connection
RF 868 MHz communication between thermostats and central unit. The gateway uses Zigbee to communicate and connects to a 2.4 GHz WiFi router for remote control and voice assistant integration (Google Assistant and Amazon Alexa).

H128 Central unit (H128-CC)
The H128-CC receives RF signals from thermostats and issues open/close commands to thermal actuators. Supports up to 8 thermostats per central unit and up to 64 actuators in total (max 10 actuators per zone).

Cascade extension
Up to 8 H128-CC central units can be cascaded using a wired link. When cascaded, additional units synchronize with the primary unit and the boiler/heat pump on/off signal is sent from the primary unit.
