## Long description

TECH i-1m mixing valve module is an expansion unit for a main controller that provides control of a single actuator in heating and HVAC mixing valve installations. The module connects to a compatible central TECH controller to expand its capability, allowing neat, compact integration into system cabinets or control panels. The white housing is designed for discreet placement and to match typical indoor equipment finishes.
Advantages
The module offers simple expansion of existing TECH controller systems without replacing the main unit, enabling control of one additional mixing valve actuator. Its compact form factor and standardized connections reduce installation time and help maintain tidy wiring. Designed for integration, the device preserves system logic and communication managed by the central controller while isolating actuator wiring to a dedicated module.
Suitable for
Expanding a TECH-compatible central controller to control an additional mixing valve actuator
Small heating zones where a single actuator is required
Retrofit installations where space is limited and a compact expansion module is preferred
Control panels and distribution cabinets in residential and light-commercial HVAC systems
Key specifications
