Page 4: Introduction
1. Introduction The control unit IVC3 is used to control an Air Handling Unit (AHU) with supply and exhaust air fans, revolving heat recovery (Rot VVX), heater (electric or water) and cooler 2. Function 1.1 Start up At start up the exhaust fan (EA) starts at set speed and the heat recovery at 100%. After 1 minute the supply fan (SA) starts and control unit starts temperature regulation. -

(Climate dep. vent., se chapter 2.8.4) 2.13 Outdoor compensated setpoint IVC3 are configurable for outdoor temperature compensation of set point. Summer and/or winter compensation are available. Two limits for outdoor temperature and a compensation value for each summer and winter can be set. -
Page 12: Alarms
Setting Description Delay Fan Alarm 0-60 min Time delay in IVC3 before a B-alarm is set and unit stops. 3.2 Fire alarm Alarm activates by external fire alarm equipment. Alarm at open contact. Result: alarm category A, unit stops. 3.3 Freeze protection alarm Freeze alarm activates if temperature drops below set alarm limit. -
Page 13: Aux-Input
Four different time events are to be set for workdays (1-5) and four events for weekend (6-7) when configured as groups. IVC3 is equipped with a real time clock for weekdays, hours and minutes. The real time clock has power back-up. -
