Digital Outdoor Thermostat
A rugged IP65 controller for heat-trace systems. Bright LED display, simple up/down setting and a dedicated freeze-protection key — ideal for snow melting, roof de-icing and pipe freeze protection in non-hazardous locations.
Reliable control for harsh conditions
One-touch freeze protection
A short press of the Fn key sets the controller straight to 4 °C freeze-protection mode.
Precise, simple setting
Set the temperature in 1 °C steps (long press for 5 °C). A red indicator shows when the heating output is on.
Fault detection & alert
On a sensor fault the display flashes “ERR” and the relay follows your configured fail-safe state (ON or OFF).
Max temperature limit
Restrict the highest selectable set point to prevent accidental over-temperature settings.
NTC calibration
Compensate sensor readings by −5 to +5 °C when replacing the sensor or using a non-standard probe.
Heating or cooling
Switchable operation mode for freeze protection, temperature maintenance or cooling applications.
