TFL 611: Continuous frost monitor with capillary sensor - 3

Product data sheet Start-up function The frost signal is added to the valve control signal connected to signal input Y. The effect of this is that before the output relay is switched to the “Frost” position (Q11/Q12), the heating valve is opened fully via signal output Y10. This switching prevents the system from turning on and off multiple times when it starts up. To ensure that the lowest temperature is always detected at the capillary tube, the temperature of the diaphragm box in the interior of the housing must always be above the capillary temperature. This is performed by the...

TFL 611: Continuous frost monitor with capillary sensor - 4

Product data sheet the frost monitor falsely detects a low temperature and goes into the “Frost” position. The same applies to a power failure or the failure of important electronic switching components. In the case of larger air duct diameters, the monitoring of a heating coil can be performed with multiple TFL 611 via: • Series connection of the TFL 611 valve control signal outputs/inputs • Series connection of the TFL 611 relay contacts Note If the relay contacts (Q11/Q12/Q14) are being operated with low voltage (U > 50 V), the following conditions apply: • For adjustment work, the...
