Two-level thermostat with function “WINDOW” meaning that output is switched in case the measured temperature is within a set range (adjustable in the range -20.. +20°C / -4°F to +68°F).
Used as protection against freezing (water-shoots, pavements, drives, pipes, etc.) heating is on when the temperature falls under set upper level (e.g. +5°C / +41°F) and off in case it falls under lower level (e.g. -10°C / -50°F, when heating is not able effectively to operate).
The thermostat is placed in a water-proof box with IP65, which allows installation outside, with in-built sensor TZ-0.
Thermostat status is indicated by LED (3 colors) under a transparent cover.
Function monitoring short-circuits and sensor disconnection (break).
Output switch contact 16A / SPDT (AC-1).
