Water
heater
Frost water
30°C
Control – Start – heater water return temperature setting, valve is opened at low temperature, regardless of the main heater control
signal (during work)
1 Kp – strengthening the return water set point controller
30s Ti – return water set point controller constant of integration
Pump protection
Active
Set protection – activation / deactivation of the pump protection control by its cyclical activation (factory setting is 30 seconds of pump
work every 7 days of idle pump)
7days Standstill time – active when the pump protection function is active
30s Start time – active when the pump protection function is active
DX
Cooler
-
30s Min standstill time – minimal standstill time of the refrigerating unit. Enter set point according to the refrigerating unit OMM
30s Min operation time – minimal operation time of the refrigerating unit. Enter set point according to the refrigerating unit OMM
10°C Min external operation temp. – min external operation temperature at which the refrigerating unit is operating.
NO Alarm contact - selectable type of NO/NC chiller alarm contact
Inactive Level II – option to activate II cooling level
Inactive
Cascading – option to activate the cascading control of 2-level DX cooler (1 – I level, 2 – II level, 3 – I and II levels), use in case of two coolers
with dierent eciency parameters
50% Level II – option to set the adjustment signal threshold setting, when the II level of cooling is activated
75% Level III – option to set the adjustment signal threshold setting, when the III level of cooling is activated (only in the cascading mode)
NOTE! The control system sends simultaneously the 0÷10VDC signal to control the DX cooling coil, in case of control with 0÷10VDC signal the „II stage” and
„Cascade” functions have to be deactivated.

30s Min standstill time – minimal standstill time of the refrigerating unit. Enter set point according to the refrigerating unit OMM
30s Min operation time – minimal operation time of the refrigerating unit. Enter set point according to the refrigerating unit OMM
10°C Min external operation temp. – min external operation temperature at which the refrigerating unit is operating.
NO Alarm contact - selectable type of NO/NC chiller alarm contact
No reaction
Defrosting:
No reaction - the defrost signal from the reversing unit does not trigger a system reaction
Low gear - defrost signal from the reversing unit causes operation on the lower gear of the unit fans
System stop - defrost signal from the reversing unit causes system stopping (with cooling down)
Mixing
chamber
Operation mode Auto
Auto – the mixing chamber is involved in the temperature adjustment process
Manual – the mixing chamber is not involved in the temperature adjustment process, setting set point of the opening level in the controller

Mixing
chamber
Heater/cooler – in the temperature adjustment process in the mixing chamber auto operation mode these functions are involved in the
following order:
1. Recovery / 2. Heater/cooler / 3. Mixing chamber
Mixing chamber – in the temperature adjustment process in the mixing chamber auto operation mode these functions are involved in the
following order:
1. Recovery / 2. Mixing chamber / 3. Heater/cooler
Min. fresh air 30% Min fresh air – dening min damper opening of the air supply/exhaust function while the system operates in the auto mode
Max. fresh air 100% Max fresh air – dening max. damper opening of the air supply/exhaust function while the system operates in the auto mode
Quick heating
Active
Quick heating – this functions enables quick heat up of the system to reach set temperature. When the quick heating mode is active and this
is necessary to activate it, the dampers block completely fresh air inow till the requested temperature is reached. This function is active only
in case of air supply-exhaust systems with recirculation.
5°C Tlim – requested temperature for quick heating function
2°C Temperature hysteresis – Tlim temperature hysteresis
