Installation instructions for the Control box for
pressure-controlled pump, part no. 809535-81/82/83, coil
heat exchangers, GOLD
1. General
The control box for coil heat exchangers consists of an
IQlogic+ module mounted inside a metallic enclosure.
Necessary wiring terminals and transformer as well as
contactors are provided for connection to external components. The metallic enclosure has cable gland screw
caps for cable entry.
2. Application area
The control box is designed for controlling a pipework
package for coil heat exchangers.
3. Installation
The control box can be mounted on a wall, air handling
unit or some other suitable place. Use four screws for the
installation (not included in the delivery).
Install an insertion-type sensor for temperature measurement on the incoming water pipe of the extract air coil.

5.3 Communication, cable adapters
Control box in combination with GOLD CX 100/120
Connect the RJ12-cable between the cable adapter and
optional bus contact marked COM6 - 11 on the control
circuit card of the GOLD unit.
Control box in combination with GOLD SD
The illustrations show electrical equipment cubicles for size
20 GOLD SD units. The principle is however the same for
all the unit sizes.
Always connect cables between cable adapters from terminal to terminal, see figure below.
The cable between units is not included in the supply.
Twisted-pair cables are recommended. Use one cable pair
for 24 V and the other cable pair for bus communication.
