Skaitmeninis termostatas W1209, -50-110 °C

Digital thermostat module with memory and LED display.


Technical parameters:

- working voltage: DC 12V
- quiescent current: approx. 10 mA
- operating current: approx. 65mA
- output: relay max 20A 125VAC / 14VDC
- controlled range: –50–110 ° C
- resolution: 0.1 ° C (-9.9 ° C-99.9 ° C) in other ranges 1 ° C
- measurement frequency: 2 × / sec
- measuring sensor: NTC (10K 0.5%), waterproof
- working conditions: –10 - 60 ° C, 20 - 85% rH
- dimensions: 48 × 40 × 14mm

Instructions for use:
- connect the supply voltage and load, the temperature will be displayed on the LED display
- press SET, the temperature starts flashing
- press - and + to set the desired temperature and press SET to confirm

Display: LLL - no temperature sensor connected, HHH - out of range

Setting other parameters:
- hold down the SET button for a long time and it is also possible to set another 6 parameters:
- P0 Relay switches at lower / higher temperature compared to set (setting C / H, default: C)
- P1 Hysteresis adjustable in the range 0.1 - 15 ° C (default value 2 ° C)
- P2 Lower limit thermostat (default value -50 ° C)
- P3 Thermostat upper limit (default value 110 ° C)
- P4 Temperature offset –7 ° C to 7 ° C (default value 0 ° C)
- P5 Delayed start 0 to 10 minutes (default value 0 minutes)
- P6 Safety shutdown at high temperature 0 ° C to 110 ° C (default value OFF), at this temperature the relay opens
- limits P0 to P6 are set with the + / - buttons

Notice:
- the temperature range of the thermostat is set by a combination of P2 + P1 (hysteresis) or P3 + P1, while only one combination is active depending on the setting of P0 (inverse relay function).

The product is not a self-functional unit, it requires professional assembly.
