C. ZONE CIRCULATOR WIRING
1. Wiring for a typical circulator zone panel is shown in
figure 7.3.
2. Note that the jumper between the hot leg of the
supply (H) and the zone circulator power input (ZC)
must be removed. Then a wire from terminal 19 of
the main panel will power all of the zone circulators.
3. If the total current rating of all of the zone pumps
exceeds 10 amps, an isolation relay must be used.
D. INTERNAL WIRING
Figure 7.4 shows the complete boiler wiring schematic
for PFC-850, PFC-1000 and PFC-1500 boilers. The
following is a list of internal wiring components and a short
description of each:
1.
User Interface Pixel Display
: A single user interface
display is located on the front of the boiler behind the
smoked lens on the jacket front panel. This interface
provides information on the boiler system and allows
the user to set the boiler address for cascade systems.
2.
Installer Interface Displays
: The installer interface
display allow the installer or service contractor to
display status information for many different values.
These displays also allow the installer/contractor to
change settings to optimize system efficiency and
operation. A detailed description of the status and
settings available is provided in Section 8 of this
manual.
3.
Interface Module
: This component provides the
following functions:
a. Alarm Contacts: These dry contacts can be used
to connect to an alarm bell, auto-dialer or other
device to alert personnel in the event of a blocking
or lockout error.
b. Analog Input: This allows a 0-10 VDC input for
external control of the system setpoint.
c. Modbus Communication: This provides two
way communication using Modbus interface for
external control of the setpoint and feedback
of system temperatures, error codes and other
values.
