User manual DAIKIN CENTRAL REMOTE CONTROLLER

[. . . ] When flashing it indicates that water circuit is not enabled to fan ventilation. economy option enabled Alarm triggered Minimum Temperature Control Valve open Heating element. If the symbol flashes it means that the heating element is on; if steadily lit it means only that the heating element has been selected Thermostat / fan status The board can be configured according to the type of unit/ system to be governed by changing some parameters. [. . . ] P01 = type of controller installation - 000: on the unit - 001: wall mounted P02 = (not used) P03 = neutral zone [20-50°C/10]; parameter used in case of configurations with automatic cooling/heating changeover according to air temperature. P04 = water sensor: - 000: not available - 001: available Based on the set value, the sensor alarm and the heating element functions will be controlled P05 = use logic ­ Digital input 1 for Cooling/Heating switching: - 000: (open/closed) = (Cooling/Heating) - 001: (open/closed) = (Heating/Cooling) P06 = use logic ­ Digital input 2 for On/Off switching: - 000: (open/closed) = (On/Off) - 001: (open/closed) = (Off/On) Press to save the new value setting or to cancel the modification After completing the modification of the parameters concerned press key to exit the procedure Once a certain time has elapsed (around 2 minutes) the thermostat will switch back into the Off status and only the saved changes will be retained. Switch the thermostat off The LCD controller can be configured in various ways according to the type of system. Various configurations can be obtained through the P00 parameter (see configuration procedure of controller parameters). Push the keys at the same time If it is correct, you will have access to the parameters COOLING/HEATING SWITCHING Four logics are present to select the thermostat operating modes according to the controller configuration setting: Local manual: user choice made through the key Remote manual: depending on the Digital Input 1 status (contact logic: see configuration parameters of board) Automatic depending on water temperature The controller can govern 3 or 4-fan speed indoor units OPERATING SPEED SELECTION Using Fan speeds: key it is possible to select the following With 3-speed configurations: where: 1 = low speed 2 = medium speed 3 = maximum speed Upon a call of the thermostat, the absence of the enabling signal will be indicated on the display by the flashing of the symbol representing the active mode ( or ) The enabling signal is ignored: If the water sensor is not included (P04 = 0) or in alarm status because disconnected In the cooling mode with 4-pipe configurations FORCED OVERRIDES The normal fan operating logic will be ignored in particular override situations that may be necessary to ensure correct control of the temperature or the unit's operation. This may occur: in the cooling mode: on-board controller (P01 = 0) and configurations with valve: the minimum speed available will be maintained even once the temperature has been reached. On-board controller and valveless configurations: after every 10 minutes in which the fan remains idle a 2 minute cleaning is carried out at medium speed to enable the air sensor to read the room temperature more correctly. In the heating mode While the heating element is on: the fan is forced to run at medium speed Once the heating element has gone off: a 2 minute postventilation cycle will be run at medium speed. ACTIVATION If this control is selected, the unit will switch on when the room temperature falls below 9°C. This procedure allows you to check whether the individual outputs of the controller function correctly. NB: Any Off command from digital input will disable this logic DISPLAY The display shows the following information Minimum temperature control selected: symbol Minimum temperature control enabled: DEFR indication Keys to change the value on the display Use the until arriving at the password for self-diagnosis (030) and press . Speed Valve Heating element Second valve Extra low speed Medium speed High speed Valve Heater valve/ Heater/extra-low speed The electronic controller outputs can be checked one by one either by observing the respective component (valve, fan. ) or verifying whether a voltage of 230 V is present at the corresponding terminals. (after a To exit the self-diagnosis procedure press few minutes the thermostat will automatically exit in any case). NB For power connections use cable w/ cross section size of 2 mm2 For digital inputs used AWG 24 cable For sensor extensions use AWG 24 shielded cable For wall mounting of the controller it is advisable to use an electric box behind the controller to accommodate the cables. NB: Prior to installation, carefully remove the protective film from the display; removal of the film may cause some dark streaks to appear on the display but these will disappear after a few seconds and are not signs of a controller defect. [. . . ] Instructions for installation: Remove the fastening screw of the controller (see figure 4). If a 503 electrical enclosure is used, pass the cables through the slot at the bottom of the controller and use the holes provided for fastening. Otherwise, in the wall where you wish to mount the controller, drill holes to match up with the fastening slots (5x8mm) on the base of the controller; pass the cables through the slot on the base and screw it to the wall (previously drilled).
