OPERATING INSTRUCTIONS --- CONSIGNES D'UTILISATION
The Unitary Package Heating, Cooling Unit has been carefully designed and built to provide reliable operating
performance when installed and maintained correctly.
CONTROL SYSTEM DESCRIPTION
The unit is controlled on both heating and cooling by a low voltage wall mounted thermostat.
Any standard 24-volt heat/cool thermostat intended to control a gas-heating unit with cooling can be made to work
with the unit as long as there are enough heating stages; this includes auto changeover and electronic
thermostats. Units 4 KW and under have 1 stage of heat, and units with 4.5 KW of heat and greater have 2 stages
of heat. Therefore, the thermostat should be chosen accordingly. A room thermostat is basically a switch used to
direct 24 volt power from the "R" terminal to its W, (or W1, W2), Y, and G terminals, according to the function
being demanded by the user. Sometimes an electronic thermostat needs to be powered with 24 volts via
connection to an additional "C" or "Common" terminal, typically if its display is backlit. If the thermostat demands
that the "C" connection be made at the thermostat wiring terminals, then please order the additional black lead
that will insert into the unit's low voltage connector, Part No. 18BK23Y-024.
Heating and cooling will be cycled on, as dictated by the setting of the wall thermostat. In this mode, the room-
side fan will run at factory-predetermined speeds for heating and cooling. The fan will be off when neither heating
nor cooling are required.
To get reasonable comfort and energy consumption, it is recommended that wall mounted thermostats be set at
21°C (70°F) for heating and 25°C (77°F) for cooling.
Over-adjusting the thermostat will not increase the rate at which a unit will heat or cool the space.
Cet appareil autonome de chauffage et de refroidissement a été soigneusement dessiné et construit pour assurer
un fonctionnement fiable quand il est installé correctement et bien entretenu.
