Rotary Dial Operation
Turn the dial to set the desired temperature — no complex menus, no programming. Reduces user errors and support calls, ideal for rental properties, senior housing, and budget-conscious projects.
Entry-Level Safety & Functional Standards
Designed to fulfill essential safety and functional standards for hydronic floor heating — offering a cost-effective solution without compromising reliability for large-scale developments.
DIP Switch Mode Changeover
Manual DIP switch instantly changes between heating (floor heating) and cooling (fan coil) modes — eliminating complex menu navigation and speeding up installation for contractors.
8-Zone Control with Wiring Centre
When connected to a wiring centre, the thermostat enables up to 8 independent heating zones — each controlled separately for tailored comfort and reduced energy waste in larger properties.
Intelligent Dual-Sensor Protection
Supports internal room sensor, external floor sensor, or both. Strict floor temperature limits prevent warping of wood or cracking of tiles — dramatically lowering post-installation callback costs.
Anti-Freeze & Boiler Interlock
Automated anti-freeze function turns on heating when room temperature falls below 5°C and stops at 8°C. Built-in interlock ensures the boiler runs only when a zone calls for heat — protecting pipes in unattended properties.
