Compact Weather-Compensated Controller AHD20
Scope of delivery/equipment:
AHD20 Controller Weather-Compensated Controller
Control of the independent mixing circuit (mixing valve and circulation pump)
Control of the additional mixing circuit (mixing valve and circulation pump).
Function:
The AHD20 is a compact, weather-compensated heating controller built into the actuator housing.
It is used to control the mixing valve and circulation pump to regulate the flow temperature during heating or cooling depending on the outside temperature.
Performance:
- 2 preset hydraulic schemes.
- Possibility of connecting up to 4 sensors (supply, outside sensor, room sensor/return sensor, power source).
- Two operating modes: weather-controlled (depending on the outside temperature) or thermostatic (depending on the room temperature).
- Intuitive setup with the keypad and color display.
- Possibility of connecting a return flow sensor and limiting the heating circuit output.
- Quick and easy installation on rotary or ball valves with a "click" system.
- Automatic screen adjustment according to the installation direction.
- Operation without a room unit is possible (depending on the heating curve).
- Possibility of a BUS connection with multiple controllers in a larger system.
- Error diagnostics and automatic activation of the alternative operating mode.
- Connection to a SeltronHome platform with remote control is possible.
