1 8 .2 HVAC Remote Panels and Panel Options
The remote panel sho u ld be mo u nted in the conditioned space in a con v enient location for controlling the air
handler. Do not locate a remote panel that contains temperat u re sensing eq u ipment in an area directly
affected by the air handler or another heat so u rce as it may interfere w ith the operation of the air handler.
1 8 .2.1 Basic II HVAC Remote
This control is typically u sed for air handlers
pro v iding make- u p air. The b u rner flame mod u lates
to maintain a constant discharge air temperat u re as
selected on the temperat u re selection dial.
FAN ON/BURNER ON Mode:
The air handler (blo w er and b u rner) operates
contin u o u sly, discharging air at the setpoint on the
discharge temperat u re selection dial. The b u rner
flame mod u lates to maintain a constant discharge air
temperat u re as selected on the temperat u re
selection dial.
FAN ON/BURNER OFF Mode:
Only the blo w er operates contin u o u sly to pro v ide
u nheated air. The b u rner remains off regardless of
temperat u re on the temperat u re selection dial.
FAN ON indicator:
Indicates that the u nit is s u pplying po w er to the

u re.
AUTO/WINTER Mode:
The air handler (blo w er and b u rner) cycle on and off

air is being discharged at the setpoint on the
discharge temperat
u re selection dial. The b u rner
flame mod u lates to maintain a constant discharge air
temperat u re as selected on the temperat u re
selection dial. The discharge air temperat u re setting
m u st be higher than the thermostat setting.
