Product description
The differential temperature controller is used in private and commercial applications as a temperature difference circuit. A typical area of application is the control of thermal solar systems (solar thermal energy).
Features
- New, modern design
- Clear menu navigation for setting the 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 from 99 to +850 °C
- Display lighting can be switched off
- Sensor calibration possible
- Relay status display in plain text
Applications
Temperature sensor 1 measures the temperatures at the solar panel and temperature sensor 2 measures the temperatures at the heat storage tank. The microprocessor of the differential temperature controller controls up to two circulation pumps or one circulation pump and one bypass valve accordingly. You operate the differential temperature controller with four buttons and a display.
