24 volt CONTROL
This panel and all heaters in the system must
be installed in accordance with all applicable
national and local codes.
Each panel is supplied with switches for 4, 8 or
12 zones (maximum two heaters per zone).
Total wiring distances must be considered and
low voltage wire correctly sized to suit the total
VA rating of the transformer. All low voltage
wire must be adequately sized for the total
load - total wiring distances up to 200 feet
must use minimum 16 gauge electrical wire,
and wiring distances over 200 feet must use
minimum 14 gauge electrical wire.
Confirm the electrical wiring system capacity with
ALL heaters ON under full load by taking voltage
readings at the ignition module terminals of each
heater . To avoid system malfunction, the volt-
age range must be within 21.6 volts to 26.4
volts (± 10%). Also ensure proper polarity.
The patio panel allows for ‘On/Off’ control of up
to 4, 8 or 12 individual heaters or zones of heat-
ers (two heaters per zone max.). If a thermostat
is to be incorporated in the system, it must be
installed in the circuit between the panel and the
heater(s). Total load of the heaters being con-
trolled must be considered in determining the
contact rating of the thermostat.
If the installation provides an individual trans-
former for each heater, size each of the 24
Volt, 60Hz transformers at 40VA. A single
transformer sized for a multiple heater instal-
lation, requires 40 VA for the first heater only,
and 30 VA for each additional heater (up to a
maximum of 16 heaters for a 500 VA trans-
former).
Example: 4 heaters wired in parallel require a
calculated 130 VA (40 + 30 + 30 + 30) -> se-
lect the closest rated transformer HIGHER
than the calculated 130 VA = 150 VA.
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 installed downstream of the control panel.
For central control of patio heater installations:
Patio heater control panels are available with
switches for 4 zones (PCP-4) 8 zones (PCP-8) or
12 zones (PCP-12). At most two heaters in a zone
can be controlled by one switch.
The panel is designed to be surface mounted IN-
DOORS only, and preferably located in a secure
staff area, beyond the reach of patrons.
WARNING
Must be used for low voltage (24V) wiring only.
To avoid system malfunction, PROPER WIRING
POLARITY MUST BE MAINTAINED.
