15. OPTIONAL 24 Vac PATIO HEATER CONTROL PANEL
This panel and all heaters in the system must be installed and grounded in accordance
with all applicable local and national 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 volt-
age readings at the ignition module terminals of each heater . To avoid system malfunction,
the voltage range must be within 21.6 volts to 26.4 volts (± 10%). Also ensure proper po-
larity.
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 transformer for each heater, size each of the 24 Vac,
60Hz transformers at 40VA. A single transformer sized for a multiple heater installation, requires
40 VA for the first heater only, and 20 VA for each additional heater.
Example: 5 heaters wired in parallel require a calculated 120 VA (40 + 20 + 20 + 20 +20) -> se-
lect the closest rated transformer HIGHER than the calculated 120 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, one switch can control maximum two heaters in a zone.
The panel is designed to be surface mounted INDOORS 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.
