WARNING!
If the plant is designed to directly connected the heat pump to a
floor system, such as underfloor heating, without intermediate
systems, the absence of condensation is not guaranteed.
13.3 Connecting to the Kita heat pump
If you want to use the PGD1 remote control panel at the same
time as the K-Touch Panel, you must use a
BMS card, purchased
separately.
If the BMS card is present, a 120Ω resistore must be installed
at the both ends of MODBUS network. To enable the HCC to
function properly, set the communication protocol to MODBUS
RTU 485 via the PGD1 panel (mask Ge01).
Referring to the μPC, make sure you
DO NOT have the terminal
ID09 connected to GND as shown in Figure 5.
With this configuration you can simultaneously use the PGD1
control panel and the K-Touch Panel.
If the K-touch panel is the only display present and it is connected
to the heat pump via the P-LAN port then it is necessary that the
ID9 contact of the µPC board is connected to the Ground, as in
figure 2.
13.4 System overview
This is an example of how to set up the plant.
