PRODUCT OVERVIEW

Bimetallic room thermostat for heating and air-conditioning installations Thermal, electrical and mechanical features Breaking capacity on opening contact,10A-250V A.C.(ohmic load) Differential: 0.5K

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 the thermostat, holding the shagreened part of the knob, turn the index with a coin, to reach the same value of the thermometer,We suggest to install the equipment at about1.5mt from the floor and far from any heat source.

PATTERN

● ①Base   
● ②Cover   
● ③Cover screw
● ④Knob Lockpins, The lock pins for scale limitation
● ⑤are to be derached from the base of the thermostat.They are Located on the fixing holes.
● ⑥Index:The fixing of the room thermostat can be done directly on the wall by screws and nags.


● B1-With N.C.contact. 
● B2-With N.C.contact and ON-OFF switch
● B3-With SPDT contact(change-over)
● B4-With change-over contact(SPDT)and ON-OFF switch 
● B7-With normally closed contact on“Winter”and normally opencontact on“Summer”plus 
“Summer-Winter”selector-switch

IMPORTANT

● ①Accelerating resistance with voltage to 220-250V a.c.
● ②This thermostat is provided with an accelerating resistance which mustbe absolutely connected in order to obtain the regulation’s performances.
● ③The terminal 4has thus to be connected to the neutral according to the diagram shown on the cover.
● ④This connection allows also the working of the pilot lamp which indicates the operation of the heating.
