Product description
The differential temperature controller is used in residential and commercial applications as a temperature differential circuit. A typical field of application is the control of solar thermal systems (solar thermal).
Features
- New, modern design
- Clear menu navigation for setting values
- Push buttons with clear feedback and button click
- Large display with indication of measured values and temperature difference
- Switching capacity up to max. 3000 W total (resistive load)
- Extended measuring range of
- 99 to +850 °C
- Display illumination can be switched off
- Sensor calibration possible
- Relay status display in plain text
Applications
Temperature sensor 1 measures temperatures at the solar panel and temperature sensor 2 measures temperatures at the heat storage tank. The microprocessor of the differential temperature controller controls up to two circulating pumps or one circulating pump and one bypass valve accordingly. You operate the differential temperature controller with four buttons and a display.
