Antifreeze Thermostat FS20, 0/+15C

TWO-PHASE FROST PROTECTION THERMOSTATS FS-20-UW
Electronic frost protection thermostat or frost monitor with switching
relay output, continuous temperature and valve output (summation output
0–10 V) and control and cascading output (0–10 V), optionally with
connection for a heating element. A IP65 resistant plastic housing with
display with the actual temperature, measuring range,
overrange/underrange of the set switch point (frost protection
temperature) and alarm indicator for "frost" or "error" (capillary
breakage, overvoltage/undervoltage), quick-locking screws and a fully
active sensor rod made of copper. The delivery scope includes a set of
MK-05-K mounting clamps for expert attachment of the sensor rod.
Measuring range: 0...+15 °C / 32...+59 °F
Accuracy: typical ± 1 K (at +10 °C)
Sensor type: 3m Copper rod active along the entire sensor length, min.
