: Support for TTL , Miconet , and Modbus protocols (/S models include RS485 for network integration).
There are two main levels of menus:
Use the or DOWN keys to adjust the value to your desired temperature. Press the SET key again to confirm and save the new value. Parameter Programming (Installer Menu) eliwell sb655 c manual repack
| | Description | Typical Value/Range | Notes | | :--- | :--- | :--- | :--- | | SEt | Temperature Setpoint : The target temperature for the system. | User-defined [LSE...HSE] | Adjustable in the Quick Menu | | diF | Differential (Hysteresis) : The temperature difference that controls when the compressor cycles on and off to maintain the setpoint. | 0.1... 150.0 | Regulator restarts when temperature reaches SEt + diF | | LSE / HSE | Setpoint Limits : The minimum and maximum allowed values for the SEt parameter. | LSE < SEt < HSE | Prevents the operator from setting a dangerously low or high temperature | | Ont / OFt | Fault-Mode Management : Defines compressor behavior (On time / Off time) if the regulation probe fails. | 0... 250 | Ont =0 & OFt =1 means compressor is always off. Ont =1 & OFt =0 means always on | | dbi | Minimum Off Time : Delay between consecutive compressor starts to protect it from short cycling. | 0... 250 min | Protects the compressor from excessive wear | | dt1 / dt2 | Defrost Interval : The time (in hours or minutes) between defrost cycles. | 0... 250 | Defrost is a critical function for heat pumps and refrigeration systems | | HAL / LAL | High/Low Alarm Thresholds : The temperature values that will trigger an alarm. | User-defined | AFd determines if these are absolute or relative to the setpoint | | H00 | Sensor Type Configuration : Selects the correct input type for the connected probe (NTC, PTC, Pt100, etc.) | 0: PTC, 1: NTC, Jtc, Htc, Pt1 | A very common first check for sensor issues |

Proper wiring ensures both operational safety and device longevity. Always disconnect the main power supply before handling electrical connections. Terminal Connections Power supply input (230Vac). Terminal 3: Common line for relay outputs. Terminal 4: Compressor output (Normally Open - NO). Terminal 5: Defrost heater output (NO). Terminal 6: Evaporator fan output (NO). Terminals 7 & 8: Ambient temperature probe (Probe 1). Terminals 7 & 9: Evaporator temperature probe (Probe 2). Parameter Programming (Installer Menu) | | Description |
: 2 PWM channels alongside dual 0-10V / 4-20mA configurable outputs for driving variable frequency drives (VFDs) or modulating condenser fans.
