Page 8: Installation
1. - Installation 1.1 - Humidity and Temperature Control Package Your ClimateMaster controller is designed for precise monitoring and control of air temperature and relative humidity (RH) within a conditioned environment. This CM3500 control system is easy to install and operate. It features a wall-mountable remote display terminal which allows you to view and adjust set points and modes of operation. -
Page 9: Auxiliary Air Heating Control Wiring
1.3 - Auxiliary Air Heating Control Wiring Note: You must use the ClimateMaster CM3500 control system to interlock the room heating system. This prevents wide fluctuations in room air temperature. It also prevents the heater from trying to heat the room while the DOAS unit is running in the cooling mode. -
Page 10: Wiring For Ventilation Air
1.4 - Wiring for Ventilation Air ClimateMaster DOAS units have a set of dry contacts to interlock with a field-supplied exhaust blower. The contacts close during the occupied mode to energize this blower. See your wiring schematics and the DOAS unit’s installation and operation manual for more details on installing and controlling ventilation air intakes. -
