Differential thermostat Thermolux, Model DT-3.1

The differential thermostat manages the operation of a circulation pump and/or the electric heating element of a domestic solar hot water heater by measuring the difference between the temperature of the water heater and the solar collector (or other heating source, such as a wood burning boiler, pellet boiler, etc.)

Features:

• Measures the temperature of the water inside the water heater, as well as the temperature of the liquid in the solar collectors, and if the temperature is 2-20°С higher (manually adjusted), it turns the circulation pump on until the temperatures are equalized.
• Equipped with two Pt 1000 thermal sensors (-50° up to +200°C), one for the water heater and one for the solar collector.

Measures a number of parameters:

• Set and actual temperature of the solar collectors and the water heater.
• The temperature that the water in the heater can reach with the optimal operation of the solar collectors.
• Critical (maximum allowed) temperature of the water heater.
• Critical temperature of the solar collector.
• Defrost temperature of the solar collector.
• Minimum temperature of the water heater.

Protects from:

• Overheating of the water heater.
• Freezing of the solar collector.
• Overheating of the solar collector.

Signals for abnormal conditions of the solar system related to high or low temperature.

Digital management of main working parameters.

No cable length limit for the temperature sensors.
