All Main Eco Compact Combi, System and Heat-Only boilers are compatible with the Baxi wired room thermostat with additional set back/timer input. It features a bi-metal thermostatic movement with an accelerator resistor for close temperature regulation, which is why it requires a three-wire connection.

Baxi Wall-Mounted 24hr Mechanical Timer

Part Number: 720971401

Another optional control compatible with the Main Eco Compact Combi is the Baxi outdoor sensor kit. Once installed on a suitable outside wall, the kit allows you to gain the efficiency benefits of outdoor weather temperature compensation control.

Baxi Programmable 7-Day Wireless Sensor (2 Channel)
