GOLD version E/F, Function Guide, All Year Comfort
1. General
The All Year Comfort function is designed for regulating
the primary water circuit for cooling and/or heating to
climate beams, perimeter climate systems, etc.
The required water temperatures can be set at the User
Level.
By enabling one of a number of different compensation
functions, the current temperature setpoints can be influenced by external circumstances.

3. Function
The function keeps the cooling or heating water in the
connected cooling and the heating system constantly at
the required temperature.
Water temperatures are measured by means of two strapon temperature sensors (see A in the illustration below) to
be mounted on the water pipe downstream of the control
valve (see B in the illustration below).
The function selector switch on the IQlogic+ module must
be set to position 7.
The base setpoint for the controller can be set in the All
Year Comfort menu accessible at the User Level. The menu
becomes accessible when any of the All Year Comfort
functions is enabled.

3.1 Outdoor compensation
To make it possible to adapt the primary water circuit
temperature to the design of the building and the outdoor air temperature, the inlet flow temperature set point
for cooling/heating water must be adjusted in line with
the outdoor air temperature according to an adjustable
performance curve. The curve can be adapted to various
conditions by means of four adjustable points. One example for heating/cooling can be viewed in the diagram to
the right.
When the function is enabled, the current setpoint from
the compensation curve supersedes the base setpoint.
The temperature by the internal outdoor sensor or by the
external outdoor sensor (if the External Outdoor Sensor
function is enabled) influences the setpoint for water temperature and controllers respectively.
3.2 Room compensation
If extra cooling or heating is required, the inlet flow temperature for the cooling or heating water can be adjusted
to save energy and increase the comfort.
The inlet flow temperature set point is influenced by the
room temperature. The set point for heating water regulation is lowered if the room temperature exceeds the preset
limit. The controller increases the set point for cooling
water regulation if the room temperature drops below the
preset limit.
On a deviation of 1 °C the water temperature setpoint is
offset 1 °C within the range of the preset P band.
3.3 Night compensation
If the premises is not occupied at night and on weekends,
the water temperature can be adjusted in order to save
energy.
The supply flow temperature set point is decreased (heating circuit) or is increased (cooling circuit) during the
preset period.

Heating
Cooling
To compensate for the loss in cooling power as the cooling
water temperature rises, the airflow can be increased to
carry away surplus heat. The increase in air flow from the
current air flow rate (for each degree the cooling water
temperature increases) is set as a percentage. This is called
the compensation flow.
3.5 Pump/valve
The pump for the heating circuit is started and stopped
according to preset outdoor limit temperatures.
It is possible to set two periods for night and weekends
respectively via two time schedulers.
The pump for the cooling circuit is operated together with
the GOLD unit and is stopped when the air handling unit
is shut down. Provision is also available for stopping the
pump for the cooling circuit with the outdoor temperature
is exceeded.
3.4 Dew point compensation (cooling water only)
The humidity and temperature in the extract air (see C in
the illustration below the section on Operation) are measured in order to ensure that condensation precipitation
will not form on cold metal surfaces.
It is possible to monitor the pumps and initiate alarms in
the event of a malfunction according to three different
principles:
1. Alarm in the event of a broken signal
2. Alarm in the event of a closed signal
3. Contactor feedback signal
By means of relative humidity and temperature readings,
the current dew point (the temperature at which moisture
condenses) is calculated. When the dew point exceeds the
cooling water temperature, the controller raises the cooling water set point to counteract condensate precipitation.
Specifications are subject to change without notice.
The valves are monitored and an alarm is initiated in the
event of a deviating valve position.
In order to prevent the pumps and valves from becoming
clogged, in the event of a longer down period, they can
be exercised at preset time intervals

See the Installation Instructions for the electrical equipment cubicle, TBLZ-2-59.
5. Settings
For basic facts on how to use the hand-held terminal, see
the Operation and Maintenance Instructions for the GOLD
air handling unit.
The functions for regulating chilled and heated water
must be activated and set under Functions/AYC.
1. Activate the function under Operating mode to select
chilled water, heated water or chilled and heated water.
2. After the required function has been activated, adjust
the required temperature under Temperature settings.
