The function of the regulator consists in activating a number of resources (power step) in proportion to the time that the evaporator water outlet by spends beyond the threshold given by CHILLER SETPOINT + (BAND / 2). The band is symmetric with respect to the value of CHILLER SETPOINT.

When the temperature has exceeded the threshold value for the duration of the parameter CHILLER INC POWER TIME, activate a power step. If the temperature of evaporator water outlet by remains above the threshold value for further TEMPO POWER INCREASE IN COLD, is another power step.

If the temperature of evaporator water outlet by remain within the temperature range determined by CHILLER SETPOINT + (BAND / 2) and CHILLER SETPOINT - (BAND / 2) the power output from the machine remains constant.

If the temperature of evaporator water outlet by remains below the threshold CHILLER SETPOINT - (BAND / 2) for the time given by the parameter CHILLER DEC POWER TIME is a step off power.

In this algorithm there is no hysteresis.

HEAT RECOVERY

The recovery function heats water using heat from the condenser that otherwise would be dispersed in the environment:

- In air (air-water units)

- In water (water-water units)

When the machine is in cooling mode (compressors on), if the water in the recovery circuit is of a sufficiently low temperature to require heat, the machine switches from normal to recovery mode. When the water temperature reaches the recovery set point, the machine switches back to normal operating mode.

Switching from normal operation to heat recovery and vice versa, takes place:

- respecting the minimum time of operation set for the two modes

- minimize compressor power (screw compressor).

After timer type set you have to go to SETUP line to actually setup the start, the end, the unit mode and water temp setup for each time band.

SETUP: according to the different timer type selected on the display there will be different lines:

IMPORTANT NOTE

For the chiller working, the time scheduling setup is always priority on the setup done by keyboard control, except the remote ON/OFF by digital input

The digital input remote ON/OFF -IF ENABLED

- is always priority on time scheduling: If the unit is in OFF mode by remote (remote ON/OFF) and the time scheduling are enabled the unit remains OFF. When you switch ON the unit by remote ON/OFF the unit starts to work following the time scheduling setup.

Time scheduling management is disabled even if the configuration mode is activated.

For instance for TIMER TYPE = 0 (daily) in submenu SETUP you have to move on MONDAY line then press ENTER and so setup for each time band the parameters showed:

TIME BAND 1 ENABLE FLAG: this parameter enable/disables the first time band
