CONTROL SYSTEM 11. CONTROL SYSTEM 11.1 General Functions and Operating Rules The DCI software is fully parametric.All the model dependent parameters are shown in Blue color and with Italic style [parameter]. The parameters values are given in the last section of this control logic chapter of the service manual. 11.1.1 System Operation Concept The control function is divided between indoor and outdoor unit controllers.
CONTROL SYSTEM Target frequency limits as a function of outdoor air temperature (OAT): OAT Range Cool mode limits OAT < 6 No limit 6 ≤ OAT < 15 MaxFreqAsOATC 15 ≤ OAT < 28 28 ≤ OAT 11.1.4 Heat mode limits No limit MaxFreqAsOAT1H MaxFreqAsOAT2H Frequency Changes Control Frequency change rate is 1 Hz/sec. 11.1.5 Compressor Starting Control Frequency Step 3 Step 2 Step 1 1 Minute 1 Minute Time Min 10 Minutes 11.1.6 Minimum On and Off Time 3 minutes. 11.1.
CONTROL SYSTEM 11.1.9 Heating Element Control Heating element can be started if LOAD > 0.8 * MaximumNLOAD AND Indoor Coil temperature < 45. The heating element will be stopped when LOAD < 0.5 * MaximumNLOAD OR if Indoor Coil temperature > 50. 11.1.10 Outdoor Fan Control The OFAN motor is an AC type that operates with 2 speeds (Low/High), controlled by Relays. OFAN speed depends on the compressor Target Frequency, and it’s set according to the following table and graphs.
CONTROL SYSTEM 11.1.12 EEV (electronic Expansion valve) Control EEV opening is defined as EEV = EEVOL + EEVCV EEVOL is the initial EEV opening as a function of the compressor frequency, operation mode, unit model and capacity. EEVCV is a correction value for the EEV opening that is based on the compressor temperature. During the first 5 minutes of compressor operation EEVCV = 0.
CONTROL SYSTEM 11.4.2 Indoor Fan Control in Heat Mode Indoor fan speed depends on the indoor coil temperature: ICTST 11.5 ICTVL ICTL ICTH ICTT Auto Cool/Heat Mode When in auto cool heat mode unit will automatically select between cool and heat mode according to the difference between actual room temperature and user set point temperature (ΔT). Unit will switch from cool to heat when compressor is off for 3 minutes, and ΔT < -3.

Lights up during operation mode (except for item in STBY indicator). 2. Blinks for 300 msec., to announce that a R/C infrared signal has been received and stored. 3.
CONTROL SYSTEM 11.10 Outdoor Unit Controller Indicators Unit has three LED’s. SB LED, STATUS LED, FAULT LED. SB LED is ON when power is ON (230 VAC), STATUS LED is ON when COMP is ON, and Blinks according to diagnostics mode definitions when either fault or protection occurs.

TROUBLESHOOTING 12. TROUBLESHOOTING WARNING!!! When Power Up – the whole outdoor unit controller, including the wiring, is under HIGH VOLTAGE!!! Never open the Outdoor unit before turning off the Power!!! When turned off, the system is still charged (400V)!!! It takes about 4 Min. to discharge the system. Touching the controller before discharging may cause an electrical shock!!! 12.
