2. General layout and setup of a system Refer to Figure 2: System with centralized domestic hot water tank on page 8 for a setup example.
Analog inputs - AI1-M(T7): Common leaving water sensor. This sensor measures the leaving water temperature to the secondary circuit. (Supplied with EKCC7-W). - AI2-M(T7): Domestic hot water temperature. (Daikin option EKCLWS). Only if you have a centralized tank and DHW must be controlled by the central control. Digital outputs - C3-DO3(T3): Contact to start the secondary pump. This contact closes whenever heating or cooling is ON. - C4-DO4(T3): Contact to energize the 3-way valve for DHW.
4.5. Backup heater? 4.6. System layout? Define here if the system has a backup heater or not. If so, select ‘Backup heating’ and define the backup heater method. INFORMATION 3 methods for the backup heating can be defined: General note on schedule settings: Method 1: Outd Temp The backup heater will be allowed to operate, depending on the outdoor temperature. - BUH allowed: Below this temperature, BUH is allowed to operate, but BUH has the lowest priority.
4.7. Control parameters Diff. LWT Heat On/Off and Diff. LWT Cool On/Off Defines the differential above/below which the system takes action to switch units ON or OFF. (TempxTime counter is started, see below). Temperature increase slaves (Temp. Incr. slaves) This parameter determines the increase (heating)/decrease (cooling) for the slaves. The setpoint of the ‘leading’ unit will be equal to the setpoint of the leaving water temperature to the secondary circuit.
To User settings INFORMATION Opens the ‘User settings’ menu with following items: This setting may also be available on the units. Make sure the setting on the unit is equal to or higher than the setting on the central control. Time/date Enter the correct time and date if you want to use the quiet mode, room heating or DHW heating schedules. Quiet mode Select OFF, ON, or SCHEDULED. The central control will send the quiet mode command to the units as selected.
6.3. Alarm menu Press the alarm button to access the following screen: 7. Alarm list Shows a list of the current alarms. Troubleshooting MDB is shown in the ‘Unit info’ menu. Make sure that the Modbus connection to the RTD-W with the corresponding address is correct. Make sure that the correct number of connected units is defined in the installer settings. U5 is shown in the ‘Unit info’ menu. Make sure that the P1P2 connection to the RTD-W with the corresponding address is correct.
