GB.809535.160321 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. 4.

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. 1 Max permissible cable length: 100 metres 2 3 1 2 3 Terminal no. 1 = Terminal no. 2 = Terminal no. 3 = Terminal no. 4 = 4 -24 VDC +24 VDC EIA-485 B BUS EIA 485 A BUS 4 GOLD SD units with control unit Control box, coil heat exchangers (supply air) Cable adapter GOLD SD units without control unit (extract air) Cable adapter Cable adapter A Twisted-pair communication cable A min. 4x0.5 mm2, max 100 metres (not included in supply).
