Gutter Heating Thermostat Eberle DTR-E 3102 IP65
Price includes 24% VAT · excl. VAT 45.16 €
Gutter Heating Thermostat Eberle DTR-E 3102 IP65 is a wall-mounted differential thermostat designed to control electric heating cables installed in gutters, downpipes and roof drainage areas. It operates the heating system only within a user-defined outdoor temperature range, helping to reduce unnecessary heating cable operation.
The IP65-rated enclosure is suitable for outdoor wall mounting. An integrated bimetallic temperature sensor measures the ambient air temperature, so no separate outdoor temperature sensor is required.
Product code: 58592808
Adjustable upper and lower temperature limits
The Eberle DTR-E 3102 contains two temperature controls connected in series:
- Temp (+), marked with a red scale, sets the upper temperature limit. When the outdoor temperature falls below this value, the gutter heating system switches on.
- Temp (–), marked with a blue scale, sets the lower temperature limit. When the temperature falls below this value, the heating switches off. It switches on again when the temperature rises above the lower limit.
In the manufacturer’s operating example, the upper limit is set to +5 °C and the lower limit to –5 °C. The heating cable then operates approximately within the critical temperature range from –5 to +5 °C.
The most suitable settings depend on the building, roof insulation, gutter construction, heating cable output and the temperatures at which meltwater is produced.
Important difference from a moisture-sensing controller
The Eberle DTR-E 3102 measures ambient temperature only. It does not detect the presence of water, snow or ice. The heating cable will therefore operate whenever the outdoor temperature is within the selected range, including during dry weather.
For a more advanced system that switches the heating on only when suitable temperature and moisture conditions occur at the same time, use a snow and ice melting controller with moisture sensors.
Outdoor installation
When used for gutter heating control, the thermostat must be installed outdoors. The recommended position is on the north-facing side of the building, approximately 1.5–1.6 metres above ground level.
The installation location must provide unrestricted air circulation. The thermostat should not be exposed to direct sunlight, continuous draughts or heat radiation. If installation on the north side is not possible, suitable shielding should be provided to protect the thermostat from direct sunlight.
Electrical installation and connection must be carried out by a qualified electrician according to the wiring diagram located inside the thermostat cover.
