6.6.1 Zone Configuration – Luminous (high intensity) Heaters
JUMPER IN POSITION 1 (P1): Up to eight single stage zones (all single-stage)
The jumper pins P1 to P5 are located inside the controller cover to the right side of the battery. The
location of the jumper in P1 … P5 determines the quantity of single-stage and two-stage zones.
With the jumper in position P1, all zones are single stage. Eight relay switches are supplied with
the controller to switch line voltage to the zone exhaust fans (field supplied) and to the zone
transformers (field supplied). Single-stage zones are controlled by the heater outputs 20-35.
Single-stage zone exhaust fans are wired in parallel to the heater zone transformer.
The 120V/24Vac zone transformer is ‘sized’ to provide sufficient power to all heaters in the zone:
40VA for first heater + 20 VA for each additional heater.
Refer to the diagram below, and the wiring diagram “Luminous Heaters – Single-Stage Zones”.
Only use fan outputs
for two-stage zone(s)*
