24 volt CONTROL PANEL
Low Voltage Wiring:
Low voltage secondary wiring from remote Trans-
former to panel must be adequately sized for the
total load. (ie 14 gauge wire)
Each model is supplied wired for individual
heater operation of 4 up to 24 heaters per panel as
required. It is not recommended to install more
than 12 heaters per zone.
Total low voltage wiring distances must be
allowed for, with low voltage wiring correctly
sized by an approved electrician to conform with
the total transformer Va rating. Proper electrical
rating in the system can be checked by voltage
readings at ignition module terminals with ALL
heaters ON under full load.
To avoid system malfunction, the voltage range
must be within 21.6 Volts to 26.4 Volts.
Malfunction of the heating system will result if the
voltage varies by more than -10% or +10% (21.6v
to 26.4v) or if the polarity is reversed.
The best mode of control for each individual
heater is by “ON/OFF” switch. If a thermostat is
to be incorporated into the system it must be in-
stalled downstream of the control panel.
Multiple heaters connected to a single 24 Volt, 60
Hz transformer, require 40 VA for the first heater
and 30Va for all subsequent additions. For
example, four heaters wired together in parallel,
equals a 130Va load, (40Va + 30Va + 30Va +
30Va), the closest rated transformer HIGHER
than the 130Va total rating is 150Va.
Total wiring distances of up to 200 feet must use a
minimum 16 gauge electrical wire, and wiring
distances of over 200 feet must use minimum 14
gauge electrical wire. (Malfunction of the heating
system will result if the voltage varies by more
than + 10% or -10%. or if polarity is reversed.)
The heater can be controlled by a line voltage
moisture proof thermostat or “off-on” switch.
Total load of all heaters must be considered in de-
termining the required contact rating of the
controlling thermostat or switch.
The heater must be electrically grounded in
accordance with the local electrical code.
For multiple Patio heater installations:
PCP-4, PCP-8, PCP-12 share the same com-
mon panel 8” x 5.75” x 4” to switch
up to a MAXIMUM of 12 heaters.
PCP-16, PCP-24 share the same common
panel 9.75” x 8” x 4” to switch up to a
MAXIMUM of 24 heaters.
Designed to be surface mounted INDOORS
only, and preferably out of the reach of pa-
trons.
WARNING:
MUST be used for low voltage wiring only.
To avoid system malfunction, PROPER WIR-
ING POLARITY MUST BE MAINTAINED,
particularly when grouping the heaters in a
zone.
