ST-FRECapillary Frost ThermostatsThe ST-FRE range of frost thermostatsprovide a switch output based on the averagetemperature detected along a two (6.56 ft) orsix metre (19.69 ft) capillary sensor.A common application is for frost protectionon fresh air intakes or airconditioning systems,to prevent the icing up of filters, fans andcoils. The capillary is fixed in a matrix acrossthe duct, in a position downstream of the preheateror frost coil.FEATURES■■Easy adjustment of setpoint■■Setting indicator■■IP65 option■■Pre-set thermostats tospeed commissioning timePart code DescriptionStandard ThermostatsST-FRE1 Auto reset, 6m (19.69 ft) capillary, Frost ThermostatST-FRE2 Manual reset, 6m (19.69 ft) capillary, Frost ThermostatST-FRE3 Auto reset, 2m (6.56 ft) capillary, Frost ThermostatST-FRE4 Manual reset, 2m (6.56 ft) capillary, Frost ThermostatPre-set ThermostatsST-FRE1-CAL Auto reset, 6m (19.69 ft) capillary pre-set to 6°C (43°F)*ST-FRE2-CAL Manual reset, 6m (19.69 ft) capillary pre-set to 6°C (43°F)*ST-FRE3-CAL Auto reset, 2m (6.56 ft) capillary pre-set to 6°C (43°F)*ST-FRE4-CAL Manual reset, 2m (6.56 ft) capillary pre-set to 6°C (43°F)*SPECIFICATIONControl range:–30 to +10°C (–22 to +50°F)Differential: ST-FRE1 & 3 2 to 16°C (3.6 to 28.8°F)ST-FRE2 & 4 2.5°C (4.5°F) – fixedSwitch rating:230Vac @ 24(10)A24Vdc @ 3AManual reset:On low temperature (ST-FRE2 & ST-FRE4)Housing material: ABSHousing dimensions: 86 x 75 x 44mm (3.39 x 2.95 x 1.73”)Capillary: Material CopperChargeVapourMax. temp. 150°C (302°F)Dimensions:2m (6.56 ft) or 6m (19.69 ft) x 1.8mm (0.07”) dia.Protection:IP44 or IP65Weight:476g (1.05 lb)Part codeST-FRE1-IP65ST-FRE2-IP65ST-FRE3-IP65ST-FRE4-IP65ST-DFKBRKData sheet: ST-FRE.pdfDescriptionIP65 Housing and ThermostatAuto reset, 6m (19.69 ft) capillary, Frost ThermostatManual reset, 6m (19.69 ft) capillary, Frost ThermostatAuto reset, 2m (6.56 ft) capillary, FrostThermostatManual reset, 2m (6.56 ft) capillary,Frost ThermostatAccessoriesPack of six additional capillary fixing clipsMounting bracket for ST-FRExVolume Price Breaks are applicableUnit Price (10+)ST-FRE1ST-FRE2Please see price listNote: All these thermostats include six capillary fixing clips as standard.* Other pre-set ranges available on request.ST-TYSpace ThermostatsThe ST-TY series of wall mounting spacethermostats are suitable for heating and/orcooling and frost protection applications.FEATURES■■Tamperproof option■■Bi-metallic switch mechanism for reliabilityCOMMON SPECIFICATIONOperating voltage: 220/240Vac @ 50/60HzSwitching differential:
