Make sure youpause in the mode to allow exhaust contacts to energize due to the delay inthe system.DAMPER CLOSE N/A N/A Positions damper to the fully closed positionCONNECT Y1–O N/A N/A Closes the Y1-O relay (Y1-O)CONNECT Y2–O N/A N/A Closes the Y2-O relay (Y2-O)CONNECT AUX1-O N/A N/A Energizes the AUX output. If Aux setting is:• NONE — not action taken• ERV — 24 Vac out. Turns on or signals an ERV that the conditions are notgood for economizing but are for ERV operation. ††• SYS — 24 Vac out. Issues a system alarmCONNECT EXH1 N/A N/A Closes the power exhaust fan 2 relay (EXH1)ALARMSAlarms display only when they are active. The menu title “ALARMS(#)” includes the number of active alarms in parenthesis ( ). When using SYLK bussensors, “SYLK” will appear on the screen, and when using 20k OA temperature sensors, “SENS T” will appear on the screenMA T SENS ERR N/A N/A SUPPLY AIR TEMPERATURE SENSOR ERRORMixed air sensor has failed or become disconnected - check wiring thenreplace sensor if the alarm continues.CO2 SENS ERR N/A N/A CO 2 SENSOR ERRORCO 2 sensor has failed, gone out of range or become disconnected - check wir-ing then replace sensor if the alarm continues.OA SYLK T ERR N/A N/A OUTSIDE AIR S-BUS SENSOR ERROROutdoor air enthalpy sensor has failed or become disconnected - check wiringthen replace sensor if the alarm continues.OA SYLK H ERR N/A N/ARA SYLK T ERR N/A N/A RETURN AIR S-BUS SENSOR ERRORReturn air enthalpy sensor has failed or become disconnected - check wiringthen replace sensor if the alarm continues.RA SYLK H ERR N/A N/ADA SYLK T ERR N/A N/A DISCHARGE AIR S-BUS SENSOR ERRORDischarge air sensor has failed or become disconnected - check wiring thenreplace sensor if the alarm continues.OA SENS T ERR N/A N/A OUTSIDE AIR TEMPERATURE SENSOR ERROROutdoor air temperature sensor has failed or become disconnected - checkwiring then replace if the alarm continues.ACT ERROR N/A N/A ACTUATOR ERRORActuator has failed or become disconnected - check for stall, over voltage,under voltage and actuator count. Replace actuator if damper is movable andsupply voltage is between 21.6 V and 26.4 V. Check actuator count on STA-TUS menu.FREEZE ALARM N/A N/A Check if outdoor temperature is below the LOW Temp Lockout on setpointmenu. Check if Mixed air temperature on STATUS menu is below the Lo Set-point on Advanced menu. When conditions are back in normal range then thealarm will go away.
