The IMI Heatmiser TM4 v2 is an advanced 4-zone programmer that serves as the central timing hub for your home. While it is the perfect companion for the UH8 Wiring Centre and DS-SB Setback Thermostats, its versatility allows it to replace any standard 230v programmer. With its intuitive touchscreen interface, the TM4 v2 makes complex scheduling a thing of the past—no manual required.

Flexible Programming: Each zone can be set to 5/2 day or 7-day mode with 4 switching times per day.
One-Touch Overrides: Includes a Boost feature for temporary extensions and a Holiday mode for energy savings while you're away.
User-Friendly Interface: High-contrast white backlit touchscreen with a simple "Copy" function to sync schedules across zones instantly.
