Section:
Outdoor unit data (works with Toshiba outdoor unit only) - displays data from outdoor unit; allows to set type and
parameters of outdoor unit; more in manual for MX communication unit
PID primary circuit
-Min meas. value (0%) - minimum measured value
-Max meas value (60%) - maximum measured value
-Min permitted action (0%) - minimum permitted output of PID regulator
-Max permitted action (100%) - minimum permitted output of PID regulator
-Max increment (100%) Maximum - increment during one period
-Sampling period (100) x10ms - sampling period
-Proportionl band (30%) - PID regulator gain
-Integrating const. (30s) - integrating constant
-Derivative const. (0s) - derivative constant
-Sym. range of insens. (0.10%) - symetric range of insensitivity
PID secondary circuit
the same as at primary circuit
Service settings 1
- T Freeze protect (15°C) - lowest permitted output water temperature (do not change !!!).
- Charg. power DHW (80%) - outdoor unit power for DHW heating
- Preheat comp. (00:00) - start delay after cold restart of outdoor unit (during this time is used bivalent source)
- Delay 1. st. biv. (00:15) - first stage of bivalent start delay
- Delay 2. st. biv. (00:18) - second stage of bivalent start delay
- Slave (OFF) - if slave mode is activated, the heat pump works in cascade
- Station number (0) - number odf station in cascade
- DHW local (OFF) - sets cascade character (if is activated); when all units in cascade are set to OFF, they are all
controlled by cascade driver and DHW is heated by central external 3-way valve. If you would like to control DHW
by one heat pump helps integrated 3-way valve without cascade driver control, set ON.
- Outdoor sen. corr. - correction of value measured by outdoor sensor
- Indoor sen. corr. - correction of value measured by indoor sensor
- T Hyster. cool. w. lim. - sets hysteresis for outdoor unit operation stop when cooling water temp. is under limit
- Comp. restart (00:10) - outdoor unit restart time limit
- Comp. restart thr. (4%) - threshold when outdoor unit is stopped and restart timer is activated
- T lim. out. w. min - minimum permitted water temperature
- T lim. out. w. max - maximum permitted water temperature
- Min water pressure - minimum operating water pressure
Service settings 2
- PWM difference (5 °C) - required temperature difference of output/input water for circulator PWM regulation
- Min circulator PWM (30%) - minimum required circulator power
- Max circulator PWM (100%) - maximum required circulator power
- Outdoor unit power - maximum outdoor unit power; value is used for minimum water flow computation
- Flow act/min - display of actual and minimal permitted water flow for heat pump operation
- Default settings - default settings reset
- Type EX (flow) - switch for EX type unit water flow computation
- MX comm. unit - enable display values and defrost detection from communication unit MX (only for Toshiba)
- Calibration - calorimeter automatic calibration; must be done when water is flowing and zero output power, and
then at stable temperature (minimum 5 minutes after tempreature setting is changed); the same temperature of
input and output water is required for calibration
Floor drying program
- five time sections which alows to set required temperature of output water for selected time; function can be
activated only in heating mode is activated.
