ProCon HT 150 / HT 225 7. Technical documentation
• Parameter 536
Setting the maximum heating capacity
It specifies the speed for the max. heating capacity of a heat
generator module and enables the reduction of the max.
module capacity.
• Parameter 541
Setting the max. heating capacity
It specifies the PW M signal in percentage for the m aximum heating
capacity of the heat generator module and enables the reduction of the
module capacity. The max. speed attained should be entered into
parameter 536. You can read off the speed in the display level of
control unit C2 (see Chap 7.5)
• Parameter 552
Hydraulic systems
It is used for adjusting the module control. This parameter
value must be at 80.
• Parameter 605
Setting of the device address (Cascade)
The device address and the segment address are a type of address
in the bus system. Each device must be correctly addressed in order to
ensure smooth communication with the connected module controls L M U
as well as the cascade and heating circuit control RVA 47 .
The device address should be assigned continuously with the
conne cted devices. Do not assign an address multiple times in a
bus segment because it will cause communication errors. Each
segment must have a master device (Address 1).
• Parameter 606
Segment address
ProCon HT is a system made up of several control units (LMU,
RVA 47). This system is the heat generator se gment and can be
constructed from a single ProCon HT or several ProCon HTs
connected in cascade . The heat generator s egment has s egment
address 0. This means that all control units in the heat generator
segment in parameter 606 for LMU and in parameter 141 for
RVA 47 have the value 0.
The heating circuit controls (e.g. RVA 63, RVA 46) in complex
heating systems constitute a segment made up of heat
consumers. You can assign the segment addresses1 to 14 to
these segments. It is better to combine several h eating circuits of a
building into one segment. Different segments are only
necessary in the case of several buildings. All controls in a
segment must have the same segment address . You can define a
maximum of 14 segments (The standard setting is 0).
• Parameter 630
Resetting maintenance request with QAA 73
You can rest the m aintenance request in queue in the control
unit with the QAA 73 by setting the Bit 6 (Parame ter 630) b6 from
0 to 1. The maintenance meter restarts afresh and displays the
maintenance request anew after one year . ( Warning ! Do not
adjust the b its . )
