Product Description

The Bromic Affinity Smart-Heat Expansion Board (part number BH3130070) is a plug-in accessory for the 1- and 2-channel Affinity On/Off and Dimmer controllers. It adds a wired Ethernet connection and a 0-10V input so the heaters can be run from a building management system (BMS) or home automation system. The board fits inside the controller, is secured with two screws and takes its power from the controller. The 5-channel Affinity controllers already have this board built in, and Alexa or Google Home control does not need it.

Features:

  • Adds wired Ethernet connectivity to 1- and 2-channel Affinity controllers
  • Adds a 0-10V terminal block for BMS or home automation control
  • Accepts a generic 0-10V signal configured in the BMS/automation system
  • Fits inside the controller enclosure, secured with two screws
  • Powered by the controller, no separate power supply needed
  • Blue jumper cable included to switch the controller to BMS control
