WIrIng Input tErMInALs

The MC Elite control will measure the sensor input based upon the options
selected from the Sensor Type in Startup menu. All other sensor terminal inputs
will be ignored. See "Sensor Type Table" on page 6.
Class 1 voltage wires (low voltage) must use a different knockout,
conduit, and path from any Class 2 voltage wires (high voltage).

system temperature sensor

Terminals (T1, COM)
• Place the Temperature Heating System Sensor in the common header where
it will register the output of the boiler/valve before any takeoffs.
• Only use the Standard Brass Tube sensor (HT #904250-00 or equivalent).
• The sensor wires can be extended up to 500' using a shielded 2-conductor 18
AWG cable (Belden #8760 or equivalent).
• Cut the shield and do not connect it at the sensor end. Only connect it at the
control end using any of the COM input terminals.
Immersion heating system sensor Installation
• Install a 3/8"ID x 1/2"NPT immersion well (HT #904011-00).
• Insert the supplied sensor probe into the well.
