Therma-Stor Products Group owner manual Electric Schematics of the Ultra-Aire XT150H

FOR HVAC INSTALLER ONLY

The pump also contains a safety float switch. The white leads from this switch extend from beneath the pump cover. This switch should be installed in series with the field wire that connects the blue (#5) lead from the Ultra-Aire XT150H to the blue (#5) lead on the control panel.

If the pump fails, this switch opens the compressor control circuit and stops water production before the reservoir overflows. The Ultra-Aire XT150H will continue to ventilate or circulate air as normal, but will not dehumidify until this switch closes.
