INTRODUCTION 2 1. INTRODUCTION Engineering Data book to ate Heat Pump System World-leading energy efficiency ­­ COP of 4. 66* Comfortable heating and hot water supply Versatile installation and operation * 11 kW model Welcome Estía to your home!Air-to-water Heat Pump System Introducing Toshiba's super-efficient space heating and hot water supply system for homes and businesses. Estía represents breakthrough thinking in intelligent heat pump and inverter technologies, by efficiently transferring ambient thermal heat from outside air to heat water indoors. [. . . ] Check DIP switch setting on the Hydro Unit board. Check the setting with the function code table. Release air completely according to the procedure. Set hydraulic pressure considering pipe height, and replenish water until manometer shows a value of set hydraulic pressure or more. Widen water path to the hydro unit or adopt a bypass valve. Set hydraulic pressure considering pipe height, and replenish water until manometer shows a value of set hydraulic pressure or more. Check expansion tank capacity compared to total water Insufficient capacity of expansion tank amount. If it is insufficient, install another expansion tank. Expansion tank failure Check the air pressure. Alarm indication E03 Alarm description and generation/reset conditions Regular communication error between hydro unit and remote controller (system controller) If there is no regular communication from the remote controller for three minutes, the hydro unit regards it as no remote controller. If there is no communication from both sides, alarm E03 occurs. Auto-reset: When successful regular communication is made Regular communication error between hydro unit and outdoor unit When serial signal from the outdoor unit cannot be received though normal serial signal is sent to the outdoor unit 1) When serial signal cannot be received continuously for 60 seconds (S code communication) 2) Communication is still not successful for 80 seconds through three retries if serial signal cannot be received for 20 seconds after new communication (f code) starts When the remote controller starts operation, serial transmission starts with the new communication format. Auto-reset: When successful regular communication is made Condensing temperature TC sensor defect If short-circuit or open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed Hydraulic heat exchanger inlet temperature TWI sensor defect If short-circuit or open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed Hydraulic heat exchanger outlet temperature TWO sensor defect If short-circuit or open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed 7 E04 F03 F10 F11 ­ 102 ­ 40-EN 7. HYDRO UNIT INSTALLATION MANUAL Engineering Data Book Alarm indication F14 Alarm description and generation/reset conditions Hot water cylinder temperature TTW sensor defect If short-circuit or open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed Floor inlet temperature TFI sensor defect If short-circuit or open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed Internal heater outlet temperature TWO sensor defect If short-circuit or open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed Floor inlet temperature TFI sensor disconnection or wrong installation (This alarm is reset by stopping operation and is checked again. ) Low-pressure sensor defect If open-circuit state continues for two seconds, an alarm occurs. Auto-reset: When normal value is confirmed Hydraulic heat exchanger EEPROM defect One mismatch is detected if there is no verification ACK after data write to the EEPROM Reset condition: This alarm is inhibited while the unit is not working. (When EEPROM1K is mounted, this alarm cannot be reset. ) Onboard expansion IC defect This alarm is not reset automatically. Group line in an hydro unit This alarm is checked during initial communication immediately after power-on. This alarm occurs immediately after operation start. [. . . ] When the " " mark appears on the remote controller for 4 seconds, the setting is completed. 2 Set STEP. · Select a STEP to be set with the STEP button, and press the SET button to determine the selected STEP. · 1 to 8: Operation program STEP number · C (Copy): Set s the operation mode for a day (0:00 to 23:59) simultaneously. · L (Deletion): Deletes all the current program operation settings (for entire week). 9 ­ 140 ­ 10-EN 9.
