Refer to page 4 for Alternate Venting Method.
8B. Electrical Connections
If the installation is new, wire the unit per the
applicable wiring diagram for line voltage (120VAC)
and control (24VAC) wiring connections.
Do not connect an external voltage source to the
HP 24 volt (T-T) wires. Install an isolation relay if
required per diagram Figure 20.
Where a HP-M2-Series in a Paloma Pak/Hytech
retrofit is connected to a single zone system, the
original transformer relay control-pak should be
removed and all field wiring connected to the unit
electrical connection junction box on the right side of
the unit. The 120VAC power input, 120VAC system
circulator output and thermostat should be wired as
outlined in figure 18.
Be sure to set the thermostat heat anticipator to
0.9 amp for single zone connection.
If a retrofit installation includes multiple zones,
any one of the options provided in this manual may be
used, or the existing transformer relay control-pak
may be utilized and re-wired according to the diagram
below. Where two wire or three wire zone valves are
used, this is the preferred wiring method on retrofits.
