POWER SUPPLY The T119 control unit has UNIVERSAL power supply, i.e. it can be supplied by 24 to 240 Vac-Vdc, 50/60Hz irrespectively of polarity in Vdc (terminals 40-42). This is obtained thanks to the use of a tested power supply unit, newly designed and manufactured, that frees installers from worrying about the correct Vac and Vdc supply. -

If the FAN is set up, the relay activates when the relative PTC sends the first signal and the FAN LED is steady ON: the relay is active for as long as the PTC senses the temperature is normal, the T119 unit keeps the relay ON for the time set during programming and the FAN LED flashes. -

FAN PTC the FAULT +FAN LED is flashing ATTENTION If the right model of PTC is not connected to the T119 control unit, the LEDs flash. The PTC temperature is nat + T = 1300 ohm. "PTC" TYPE TEMPERATURE SENSORS The PTCs can be compared to bimetallic thermostats where the contact opens and closes at the approximate temperature, defined as their operating characteristic (NAT=operating temperature). -
