- If incoming voltage is less than 216V, the Primary Power Tap at the transformer must be changed from “240V” spade to “208V” spade.
- Failure to do so will cause control voltage of 18v or less, which will cause erratic (or NO) operation in the contactors and relays.
- Will also cause thermostat failure. Please have an electrician wire your Office Container to ensure safe & proper electrical hookup.
