Thermostats Basic Terms and Technical Information Characteristics ALCO-thermostats are electric circuit control devices which open or close an electric contact depending on temperature changes at the bulb. Description of bulb charges The application range of thermostats in mainly determined by the charge. Accordingly various bulb shapes and sizes are necessary. x x Vapour charge, bulb type A, E, P The thermosystem is filled with a medium in vapour phase. A thermostat with vapour charge operates in accordance with temperature changes at the bulb as long as the bulb is the coldest part in the whole system (bellows, capillary tube, bulb). ALCO thermostats are equipped with a bellows heater (8 kohm, 30 V) to avoid such conditions (not for TF and Explosion proof types). On applications with low current the bellows heater has to be removed. Max. bulb temperature is 50 C (70 C for bulb type E). Response time is very fast. Liquid charge Bulb type D : This charge only reacts on temperature changes at the bulb. The max. bulb temperature is 00 C. Bulb type C: Bulb must be warmer than capillary tube and bellow (i.e. for heating purpose). Max. bulb temperature is 0 C. Response time is fast. x Adsorption charge, bulb type F This charge only reacts on temperature changes at the bulb. Max. bulb temperature is 00 C. Response time is slow but perfectly suitable for common refrigeration systems. Adjustment of switching points A thermometer should always be used for comparison when adjusting the switching points on temperature controls. The setting scale on the device is intended to serve for orientation, showing the setting range of the upper switching point t max in C and F and the value of the temperature differentialvt in K as difference between the upper switching point t max and the lower switching point t min. The upper switching point t max has to be adjusted on the scale, whereas the lower switching point t min is given by adjustment of the desired switching differential Vt. The formula is: Upper switching point Differential = Lower switching point t max Vt = t min Important! The differential Vt mentioned on the differential scale and in the technical data refers to the upper part of the setting range and the upper switching point. In the lower part of the setting range an increase of the differential Vt can be expected. The lowest possible lower switching point t min is mentioned in the selection tables and is helpful to select switching points with large differentials Vt in the lower temperature range.

Function of contacts SPDT - On temperature rise above setting - opens and - closes. - On temperature drop below setting - closes and - opens. SPDT - with off switch AUTOmatic - STOP SPDT with manual reset min. - On temperature drop below setting - closes, - opens and latches. - The device can be manually reset when the temperature has risen at least K above setting. SPDT - with bellows heater include a 8 k Ohm, 30 V ac/dc resistor SPDT with manual reset max. - On temperature rise above setting - opens and - closes and latches. - The device can be manually reset when the temperature has dropped K below setting.
