PRIOR ASSEMBLY NEEDED

Please keep these instructions for future reference.
Equipment assembly and wiring is required before using this guide.
Please make sure control circuit transformer is properly setup.
Please ensure your board has the latest firmware. Latest firmware revision can be found at https://intelligencontrols.com/resources
For assembly, please consult intelliGen installation & operation manual.

IMPORTANT!

BRAZING PIPING CONNECTIONS

CONTROL TRANSFORMERS COME WITH THE VOLTAGE TAP ON 240V (as shown)

If your site has less than 215VAC, the tap will need to be moved to 208V in order to ensure 25VAC to 29VAC power to IntelliGen board.

ANTI-SHORT CYCLE TIMER DELAY RELAY IN CONDENSING UNIT HEATCRAFT
25010301 Intelligen Refrigeration Controller - CONDENSING
UNIT

Some condensing units may have an Anti-Short Cycle Time Delay Relay (ASCT) installed for compressor short cycle protection. These time delay relays should be removed when connecting the condensing unit to unit coolers with intelliGen installed. The intelliGen control has compressor short cycle protection functionality built-in, and failure to remove the electro- mechanical ASCT relay can result in system run-time conflicts and negative impacts to system performance.
