ProCon HT 150 / HT 225
3. Start-up
3.1 Operating ProCon HT 150 / HT 225
3.2 Setting boiler and room set point value
ProCon HT 150 carries two 75 kW heat generator modules as
well as a cascade and a heating circuit controller (RVA 47). Each
heat generator module has a module control unit (LMU). The
LMU controls and regulates the heat generator module.
ProCon HT 225 carries three 75 kW heat generator modules as
well as a cascade and a heating circuit controller (RVA 47). Each of
the three heat generator modules has a module control unit (LMU).
The LMU controls and regulates the heat generator module.
By means of the corresponding control unit (AGU) each LMU
can be manually switched on or switched to control stop for the
purpose of adjustment.
Con HT 150 / HT 225 control panel houses the cascade
control, three AGU's, the main switch, the fuse and a pressure
gage.

RVA 47 assumes the cascade function, weather control, the
heating program and the domestic water program. The functions of
the controller are described in detail in MBW RVA 47.320
instruction manual included in the scope of delivery.
The boiler and room set point value functions are described in detail
in the installation/operation/maintenance RVA 47.320 instruction
manual included in the scope of delivery.
3.3 Setting domestic water temperature
The domestic water temperature function is described in detail in
MBW RVA 47.320 instruction manual included in the scope of
delivery.
3.4 Programming ProCon HT 150 / HT 225
All the parameters associated with the heating system should be
set in the RVA . The functions of the controller are described in
detail in MBW RVA 47.320 instruction manual included in the
scope of delivery.
The LMU can only be programmed by means of an optional QAA
73 indoor unit. Programming of the LMU is only necessary if you
need to replace an original component.
Unused heating circuits must be switched off in
parameter 17
(Heating characteristics). Otherwise heat will be
provided for nonexistent heating circuits.

LPB bus
Allocation of device and segment addresses:
The LPB bus organizes the connection of several heat generators
and heating circuit controllers by allocating distinct addresses to the
cascade and heating circuit controller RVA 47, the module control
unit LMU as well as the heating circuit controllers. An expert
allocates the addresses during start-up. Two parameters (Device
address 140 and segment address 141) are available for this
purpose. The allocation is carried out according to the following
rules:
1. The controllers of the heat generator receive segment address
0.
The controllers of the heating circuits receive segment address 1.
The address format consists of two points for the segment
address and two points for the device address separated by a
period e.g. RVA 47 with the address 00.01
2. DRVA 47 always receives the Device address
1. RVA 47 can address up to 12 LMU's.
The LMU of the heat generator module receives the Device
addresses 2 upwards irrespective of whether it is the master
or slave cascade boiler.
3. Never allocate an address twice.
