6.6.4 Zone Configuration – Luminous (high intensity) Heaters
JUMPER IN POSITION 4 (P4): Three two-stage zones + two single-stage zones
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 P4, three zones are two-stage, and two zones remain for 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). Three additional field supplied relay
switches (P/N: JS-0568-CC) are required to power the exhaust fans for the two-stage zones.
The fans for the two-stage zones are controlled by the controller fan outputs 10-11, 12-13 and
14-15. Fans for the single-stage zones are controlled by the heater outputs 32-35. 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 20 VA for each additional heater. A separate transformer is required for
each of the Low- and High-stage zones in two-stage Zones 1 and 2.
Refer to the diagram below, and the wiring diagram “Luminous Heaters – Two-Stage Zone”.
Only use fan outputs
for two-stage zone(s)*
