Common Control Sequences
The next control sequence explanations are normal for steam/warm water unit heating units in garage or workshop programs:
>>Intermittent Fan Operation - Hot Coil
Whenever a room thermostat requires warmth, the motor is vitalized. Warm water or steam is continuously provided towards the unit heater, even if the motor isn't running. Once the thermostat is content, the motor is p-vitalized.
>>Continuous Fan Operation - Intermittent Hot/Cold Coil
Whenever a room thermostat requires warmth, a valve is opened up, permitting steam or warm water to go in the system heater. Once the thermostat is content, the valve is closed. The fan runs continuously.
>>Intermittent Fan Operation - Intermittent Hot/Cold Coil
Whenever a room thermostat requires warmth, the motor is vitalized. Simultaneously, a valve is opened up permitting steam or warm water to go in the system heater. An aquastat might be connected to the supply or return piping to avoid fan operation before the coil is adequately heated to prevent cold air delivery. Once the thermostat is content, the valve shuts and also the motor is p-vitalized.
3) How do you figure out how much warmth a warm water unit heater will generate with different entering warm water temps?
ANSWER: Warm water unit heating units will also be combined with steam. The main warm water unit heater producers rate their capabilities using 2 psi steam. For instance, a Modine model HSB33 will produce 33,000 BTUs when it's connected to two PSI steam. Another example: A Sterling model HS120 will produce 120,000 BTUs when connected to two PSI steam.
