• Suitable for temperature control in plant rooms and boiler rooms
• Ideal for integration with electrical distribution and control panels
• Used with fan‑coil units requiring simple on–off switching
• Can be used for room‑level control in office and commercial spaces

What supply voltages can it tolerate during installation?


The unit is designed to be powered from 230V AC and has a maximum supply voltage rating that aligns with typical mains limits.

How does it Interface with external sensors?


It accepts a single external input enabling connection to a remote temperature sensor for more representative room measurements.

What outputs are available for controlling heating or equipment?


Two on–off outputs are provided so separate devices or stages can be switched independently.

What environmental conditions limit its placement?


Operational ambient temperature is constrained between +5°C and +35°C and the IP30 enclosure requires installation in non‑exposed indoor locations.

Which approvals ensure conformity for industrial use?
