Polar Bear Design driver for Control4

Overview

This driver allows integration of Polar Bear thermostats (such as Zentium and Ursium) into a Control4 SmartHome system. The Polar Bear thermostat is a 2-zone thermostat with a simple and clear interface with a rotary dial for intuitive user control. The thermostat is typically configured for its desired operation by the installer (eg heating / cooling / towel-rails) and the configuration is then discovered by the Control4 driver, simplifying integration into Control4.

This driver supports operation of Polar Bear Thermostats as a stand-alone system, without requiring interaction any other BMS system. This is achieved in several means (please consult Polar Bear Design for further details)

• AC fan-coil units are directly controlled from a secondary Modbus interface on the thermostat
• Manifold relays are controlled via an RTU Manifold controller, with assignment of relay ports to thermostat being configured in the Control4 driver

The Polar Bear thermostat and RTU Manifold controller connect via Modbus. The driver supports a single Modbus interface, supporting up to 32 devices (thermostats and manifold controllers). If the system is split into 2 (or more) Modbus lines, then a separate communication driver is required for each Modbus interface.
