Procon
. AGU. C-I M BMS I
(Part No – .-)
With the use of an AGU. Clip-In Module, the boiler controller can
communicate with a BMS System.
This Clip-In Module has three V (Hz) progra mm able outputs
that can be con gured to respond to the operational status of the
boiler, for remote monitoring, such as, Healthy, Run and Lock-Out.
This Clip-In Module can also accept a -V dc or mAmp input
signal for Set-point Temperature, or Percentage Output control.
Please refer to instructions supplied with the Clip-In Module for pro-
gramming instructions (Ref. - LAGU).
. OCI C-I M LPB
C
(Part No – .-)
With the use of an OCI Clip-In Module, the Optional Extra Con-
trols detailed from . onwards can also be utilized.
One Clip-In Module is required per boiler in a Multiple Boilerarrange-
ment.
Please refer to instructions supplied with the Clip-In Module for pro-
gramming instructions (Ref. - LOCI).
. RVA C C (G) H
The RVA Cascade Controller (Grey) is a comprehensiveunit that can
be wall or control panel mounted, and can control upto twelve Procon ,
, & boilers. The RVAis supplied with No QAD System Sensors
( ow & return) anda QAC outside air sensor. Each Procon boiler MUSTbe
tted with an OCI Communication Clip-In Module, see item ..
In addition to boiler control, the RVA can provide the drivesignal
for a heating circuit pump and can provide control for storeddomestic
hot water, with the RVA providing the drive signal fora hot water
primary circuit pump.
External control input to the RVA can be by either, a VoltFree con-
tact (e.g. time clock), -v analogue input, a QAA, QAA or QAA
Modulating Room Unit.
Heating ow temperatures are weather compensated variable (QAC supplied), if constant temperature is
required, a
Ω resistor needs to be installed in place of the outside air sensor.
If more than twelve boilers need to be controlled, then additional RVA Cascade Controllers can be con-
nected to the rst unit in a ‘Master/Slave’ arrangement. Each subsequent ‘Slave’ RVA can control up to twelve
boilers each.
Standard features include Pump Overrun, Boiler Load Rotation, Frost Protection, and Pump Exercise program.
Please refer to instructions supplied with the RVA for programming instructions (Ref. - LRVAQR/LRVAS).
