Electronic thermostat, multi range, control and manual reset action, for incorporation, NTC sensor
This electronic thermostat for incorporation has been designed to replace electromechanical thermostats. It is mounted with two screws M4 at the same distance 28 mm, uses a 6mm dia. shaft with 4.6mm flat with the same length, and its rotation angle is 230°. Therefor temperature ranges are quite the same as the bulb and capillary thermostats Its electrical rating (16A) is identical.

Main features
This electronic thermostat for incorporation has been designed to replace electromechanical thermostats. It is mounted with two screws M4 at the same distance 28 mm, uses a 6mm dia. shaft with 4.6mm flat with the same length, and its rotation angle is 230°. Therefor temperature ranges are quite the same as the bulb and capillary thermostats Its electrical rating (16A) is identical.
It additionally features adjustable temperature differential, and heating or cooling relay output setting, and control or manual reset action can be set.
Action: On-Off.
Size: 60 x 43 x 23 mm.
Temperature sensor: NTC thermistor, 10Kohms @25°C, B(25-50)= 3380.
Temperature ranges setting: Temperature range selection is made by dip switch on the printed circuit. 230° angulation set span.
Temperature ranges: -35+35°C (-30+95°F); 0-10°C (32-50°F); 4-40°C (40-105°F); 30-90°C (85-190°F); 30-110°C (85-230°F); 20-125°C (68-260°F).
Temperature differential: Adjustable, by potentiometer with front access, from 0.25°C to 2.5°C (0.4 to 4°F) for temperature ranges 0-10°C (32-50°F) and 4-40°C (40-105°F) and 0.5 to 5.5°C (0.9 to 10°F) for other temperature ranges.
Accuracy: +/-1% of scale (NTC sensor tolerances not included).
Control or manual reset selection: can be selected with a miniature dip switch on the circuit.
Power supply: 180 to 240V, 50Hz or 60Hz.
Relay output: SPNO, 16A250V resistive, 100000 cycles.
Relay action: Heating or cooling, open or close on temperature rise output relay action can be selected by a dip switch with access from front side.
Ambient: -20+50°C, 10-85% RH.
Power: <2W.
Electrical connections:
- Power supply and power relay: 2.5 mm² screw terminal
- Temperature sensor: 1.5 mm² screw terminal
Manual reset: 1.5 mm² screw terminal block.
Adjustment shaft: The thermostat is shipped with a dia. 6 mm with 4.6 mm flat shaft, length 11 mm, assembled. Included is also a set of: one 15 mm shaft, one 28 mm shaft and one screw driver adjustment shaft.
Standards: Comply with LVD and EMC (CE certificate by TÜV), upon the following standards:
- EN55014-1: 2006+A1+A2;
- EN55014-2: 1997+A1+A2;
