SPC’s Advanced Proportional Controller for Fan-Assisted Heaters
The SPC Modulo v3 is our latest proportional controller, specifically engineered for fan-assisted heaters requiring precise airside control via 0 to 10V analogue signals. This controller optimises performance for the SPC range of heating units, which utilise energy-efficient EC/DC fans to deliver enhanced comfort, energy efficiency, and air distribution.
User-Friendly Thermostat Control
The Modulo v3’s intuitive thermostat design prioritises simplicity. The thermostat is energised with a touch in the top-right area, while setpoint adjustments can be made with bottom left and right touch areas—no other settings are required, making it easy to manage.
Automatic Fan Speed Control
By automatically adjusting the fan convectors’ rotational speed based on the difference between the sensed and setpoint temperature, the Modulo v3 creates a comfortable environment without additional manual adjustments.
New Optional Relay Box for On/Off Control
With the Modulo v3, a relay box with a volt-free contact is available, allowing for on/off control of a water valve providing greater control over fan convectors in heating systems.
Lockable Transparent Cover Box
For settings that need security, a lockable transparent cover box is available, ensuring thermostat access is restricted when required.
Energy Efficiency at Your Fingertips
The graph shows how the controller varies the speed of the fan in response to the difference between the actual temperature and the setpoint temperature. The fan speed is continuously varied within the proportional band to match heat output to the required load precisely.
