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.
