    1. Technical Data:

    1).Voltage:AC230V +10%~-15%,50/60Hz

    2).Temperature scale:0~40℃

    3).Control voltage signal:AC230V

    4).Ambient temperature:-10℃/+50℃

    5).Dimensions:H/75, W/75, D/25MM

    6).Protection: IP20             

    7).The thermostat free of maintenance.

     

    2. Thermal, electrical and mechanical features:

    Breaking capacity:

    NTL-7000A:

    on opening contact, 16A-250V A.C.(ohmic load)

    on closing contact, 10A-250V A.C.(ohmic load)

    Differential:4K

     

    NTL-7000B:

    on opening contact, 6A-250V A.C.(ohmic load)

    on closing contact, 4A-250V A.C.(ohmic load)

    Differential:4K

     

    3. Temperature's scale adjustment

    After almost two days from the installation, to obtain a precise scale adjustment, measure the room temperature with a reference thermometer, placed aside to reach the same value of the thermometer, We suggest to install the equipment at at about 1.5m from the floor and far from any heat source.

     

    4. Important

    ● Accelerating resistance with voltage to 220V-250V a.c.

    ● This thermostat is provided with an accelerating resistance which must be absolutely connected in order to obtain the regulation's performances.

    ● The terminal 4 has thus to be connected to the neutral according to the diagram shown on the cover.

    ● This connection allows also the working of the pilot lamp which indicates the operation of the heating.
