Thermostat Controller

  • 6995

We currently have 1 in stock.


This module contains three Panasonic AQH3213 AC Solid State Relays. A Solid State Relay (SSR) is a voltage controlled switch. These three relays can control an HVAC system and can turn on and off the FAN, HEAT, and COOL. The module also contains a TMP102 Temperature Sensor. With this module you can set up a really great intelligent thermostat.

It also contains an EFM32WG842 Gecko low power microcontroller and two RS232 serial ports allowing it to be daisy chained in a network.

The TMP102 Temperature Sensor is accurate to 0.5°C/0.9°F over a range of -25°C to +85°C (-13°F to 185°F).
