This Method allows direct modulation of the boiler based on a 4-20 mA control signal. A control
capable of transmitting a 4-20mA/0-10 VDC control signal for the purpose of modulating a boiler
and to control a common system temperature must be used with this method.
NOTE: If using a 0-10 VDC signal multiply any references to current in the manual by .5. Example:
5ma * .5 = 2.5 VDC
