Presentation

PROMATIC^® WDC is a modern weather compensated heating controller with one or two mixing heating circuits, for domestic hot water warming with boiler and solar system and up to two heat sources. WDC is designed for demanding installations and allows user to choose among fifty-two pre-set hydraulic schemes.

For a quick and easy start, a start-up wizard is installed, that guides user through the controller setting in only three to four steps. The controller can be switched to simulation mode, where you can simulate the temperatures of individual sensors and monitor the controller’s response.

User functions

Party operation mode

Party operation mode is selected to extend daily or comfort mode of space heating. You can also set the time of the Party operation model.

ECO operation mode

ECO function allows heating at a lower or energy saving temperature. You can also set the time of the Eco operation mode.

One-time d. h. water warming

The function switches on the domestic hot water heating instantly.

Holiday operation mode

The function allows the heating to be set at a specific energy saving temperature for a specified number of days.

Anti-legionella program

The controller ensures the medium is bacteriafree by periodically
heating water to 60 °C.

Heating system protection

The controller ensures periodical start-up of pumps and valves during inactive period as well as protection of the solar panels, and the heater against overheating or freezing.

PC Interface

Through dedicated USB inverter the PROMATIC^® WDC controller can be connected to a PC. The accompanying Selcontrol software allows setting and monitoring of controller operation using a PC. The solution also operates in the SeltronHome environment.
