JAGUAR MULTIPLE BOILER SYSTEM CONTROL

The two common control methods for Jaguar Multiple
Boiler Systems are listed below.
1. Jaguar Link: Built- Every Jaguar Model
J-390C boiler control has built-in cascading abilities
for up to a total of 8 Jaguar boilers. Utilization of this
feature requires one optional supply water sensor
(Slant/Fin Part # 833-433) per Jaguar Multiple Boiler
System. The boiler is programmed as the "master
boiler" while the other Jaguar boilers are called the
"follower boilers". The master boiler controls the sys-
tem water temperature as well as determining what
Jaguar boilers should operate and what their fuel
input should be.
For details on wiring and programming using this
method go to Section 10 on page 19 of this manual.
2. Using External BMS Signal: An external control
with a 0 to 10 Vdc signal may be used to control a
Jaguar Multiple Boiler System. Utilization of this fea-
ture requires one optional interface kit (Slant/Fin Part
# 830-130) per Jaguar Boiler. This method facilitates
control of a Jaguar Multiple Boiler System using
external control such as a building automation sys-
tem. The external control determines system supply
water temperature, what Jaguar boilers fire and the
fuel input is for each Jaguar boiler.
For details on wiring and programming using this
method go to Section 11 on page 28of this manual.
