PART 6: FIELD WIRING
FIELD WIRING
A. FIELD WIRING COMPLIANCE REQUIREMENTS
INSTALLATION MUST COMPLY WITH:
1. National Electrical Code and any other national, state, provincial or local codes or regulations.
2. In Canada, CSA C22.1 Canadian Electrical Code Part 1, and any local codes.
B. FIELD WIRING
All the wiring connections made to the Phoenix Evolution in the field are done on the field connec-
tion board located on the right side of the cabinet. The cabinet has multiple knockouts available to
route field wiring into and out of the field connection board. The control provides a pump output
thermostat and outdoor sensor inputs to operate the central heating system.
C. LINE VOLTAGE WIRING
1.
Connect the normal
Incoming Power
to the terminals marked as shown in Figure 6-1. A line
voltage fused disconnect switch may be required to be externally mounted and connected
according to local codes and standards.
2.
Connect the
Central Heating Pump
as shown in Figure 6-1 the terminals marked CH/DHW
PUMP. The connection shown are suitable for a maximum continuous pump draw of 3 amps
at 120 volts. If the pump requires more current or voltage other than the 120 volts supplied,
an external motor starter will be required.
3.
Please note that the solar pump connectors on the field connection board are not functional
at this time.
D. LOW VOLTAGE WIRING
1.
Make all low voltage connections to the terminal strip located on the field connection board
(shown in Figure 6-1) as outlined below.
2.
The
Room Thermostat
should be connected to the terminals marked T STAT (shown in
Figure 6-1). Alternately, any dry contact closure across these terminals will cause the unit to
operate the hydronic heating module. NOTE: Caution must be used to ensure neither of the
terminals become connected to ground. Mount the thermostat on an inside wall as central as
possible to the area being heated, away from drafts or heat producing devices such as a
television etc. which could influence the ability of the thermostat to measure room
