6.6.4 Zone Configuration – Luminous (high intensity) Heaters
JUMPER IN POSITION 5 (P5): Four two-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 P5, all four zones are two-stage. Eight relay switches are supplied with
the controller to switch line voltage to the zone transformers (field supplied). Four 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, 14-15
and 16-17.
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. A separate transformer is required for
each of the Low- and High-stage zones in each of the 4two-stage zones.
Refer to the diagram below, and the wiring diagram “Luminous Heaters – Two-Stage Zone”.
Only use fan outputs
for two-stage zone(s)*
