II.3.2.3 User interface panel SECTION II: INSTALLATION AND MAINTENANCE TCAE-TCAES 470÷4160 cooling adjustment set Fig. 10 1 = DISPLAY: displays the value of each parameter (e.g. outlet water temperature, etc.), triggered alarm codes and the status of all machine resources. 2 = ON/OFF, RESET - DOWN: act on this key to switch on, off and reset any alarms triggered on the unit. It also allows you to scroll down the parameter values. 3 = MODE - UP: act on this key to select the function mode of the unit (stand-by, summer or winter cycle). It also allows you to scroll up the parameter values. 4 = summer LED: indicates that the unit is running in the cooling cycle. 5 = winter LED: indicates that the unit is running in the heating cycle. 6 = compressor and defrosting LED: indicates that the compressors are running or that the compressors are subjected to a time delay (the LED flashes fast). On THAE-THAES versions running in the winter cycle, it indicates that the unit is defrosting (the LED flashes slowly). 7 = evaporator heating element LED: indicates that the heating element is activated. 8 = power supply LED: indicates that the unit is connected to the power supply. N.B.: The user may access the parameters regarding the unit working set points. Thanks to a password, technical service personnel may access the unit management parameters (authorised personnel only). II.3.2.4 Setup and adjustment instructions The unit is adjusted according to the condenser/evaporator inlet water temperature. The temperature is controlled by proportional side band adjustment. Once the set point and the water temperature control differential have been selected, the controller manages the available compressors in order to meet the thermal load required by the user. TCAE-TCAES 230÷260 cooling adjustment THAE-THAES 230÷260 heating adjustment THAE-THAES 470÷4160 heating adjustment By acting on the switches and the keyboards the installer may carry out the following operations: • supply power to the unit; • start up; • change/select the function mode; • set the summer set point; • display any alarms; • display the status of the main machine components; • stop the unit; • disconnect the unit from the mains power supply. Any other operation must be carried out by qualified personnel authorised by RHOSS. II.3.2.5 Power supply to the unit Act on the main switch by turning the yellow handle clockwise by 90°. • The “power supply” LED lights up. II.3.2.6 Disconnection from the mains power supply Act on the main switch by turning the yellow handle anticlockwise by 90°. • The “power supply” LED switches off indicating that the unit is no longer connected to the mains power supply. II.3.2.7 Start up Press ON/OFF, RESET-DOWN for 2 seconds. • The LED relative to the function mode active when the appliance was last switched off lights up and the display shows the inlet water temperature. • The compressor time delay LED starts to flash. • After a certain time delay the LED remains lit indicating that the compressor has started to run. 14
SECTION II: INSTALLATION AND MAINTENANCE II.3.2.8 Stand-by Press MODE once or twice according to whether the function mode is winter or summer. • The LEDs indicating the summer and winter modes switch off. • The water inlet temperature continues to be displayed. II.3.2.9 Changing the function mode (THAE-THAES only) Press MODE. • The LED relative to the active function mode switches off and the LED relative tot eh selected function mode lights up. • The compressor time delay LED begins to flash. • After the time delay has elapsed the LED remains lit indicating that the compressor has started to run. II.3.2.10 Stopping the unit Press ON/OFF, RESET-DOWN for 2 seconds. • The compressor and active function mode LEDs switch off. • The “power supply” LED remains lit indicating that the unit is connected to the power supply. II.3.2.11 Adjustment variables which can be edited from the keyboard Parameter function Adjustment limit Set value Coo Cooling set point 7 ÷20 °C HEA Heating set point 34 ÷53 °C H49 PSS Remote summer/winter enablement Password (technical service) 8°C (470÷4160) 9.5°C(230÷260) 44°C (470÷4160) 42.5°C(230÷260) 0 Summer and winter set points To modify the parameters it is necessary to access the 4 levels represented in the diagram below. To do this, proceed as follows: • press the MODE-UP and ON/OFF, RESET-DOWN keys simultaneously to move down through the levels (from 0 to 4); • press the MODE-UP and ON/OFF, RESET-DOWN keys simultaneously for 2 seconds to move up through the levels (from 4 to 0). It may be necessary for the installer to modify one of the parameters to suit specific operating requirements. The following example explains how to modify the HEA parameter (heating set point). Proceed as follows: ○ Press the MODE-UP and ON/OFF, RESET-DOWN keys simultaneously. • The compressor, defrosting and heating element LEDs flash. • The SET label is displayed. • Use the UP/DOWN keys to select the label to be modified (in this case SET). ○ Press MODE-UP and ON/OFF, RESET-DOWN simultaneously. • The Coo label is displayed. • Use the UP/DOWN keys to select the sub-label to be modified (in this case HEA). ○ Press MODE-UP and ON/OFF, RESET-DOWN simultaneously. • The value of sub-label HEA is displayed. • Act on the UP/DOWN keys to change the value of the HEA parameter (within the preset limits). • After setting the desired value press MODE-UP and ON/OFF, RESET-DOWN simultaneously three times for 2 seconds. All the other available parameters may be modified using the same procedure. IMPORTANT! Changing or adjusting machine function parameters must be carried out with the utmost care so as to avoid conflict with other parameter settings. ○ For example, if you set the Coo parameter at 0°C, it is necessary to also change the antifreeze set point parameter (which can only be changed by authorised personnel in possession of the protection password): • A11 (antifreeze alarm set point). To prevent machine shutdown caused by the antifreeze protection, displayed by the EO5 alarm. Whenever the A11 parameter is assigned a value below 3°C it is essential to use water mixed with a suitable percentage of ethylene glycol. level 0 (display) level 1 (labels) level 2 (sub labels) level 3 level 4 display of sensor temperature or active alarm Set point: SET Cooling set point: Coo Cooling set point value Heating set point: HER Heating set point value sensor value:TP Sensors: T01÷T06 Sensor value alarms: Err Active alarms: Exx digital imput: Id Parameters: i01÷i11 digital imput status parameters: Par Configuration par.: CnF Parameters: H49 Parameter value Compressor par.: CP Parameters: C03 e C04 Parameter value Fan parameter: Fan Parameters: F25 Parameter value Alarm parameter: ALL Par.: A04, A06, A11 Parameter value Pump parameter: PUP Antifreeze parameter: Fro Parameters: r02÷r17 Parameter value Defrosting parameter:dFr Parameters: d02÷d09 Parameter value Expansion Board parameter Parameters: n01÷n07 Password: PSS Working hours: OHR Password value Comp. work. hours: OH1÷OH4 Pump working hours: OHP Number of hours Number of hours 15
