GOLD version E/F, Function Guide,
SMART Link/AQUA Link
1. General
The SMART Link function is intended for use in controlling
the times, temperatures, etc. as well as reading the alarms
and settings of a Swegon chiller/heat pump via a handheld micro terminal and web page in a GOLD air handling
unit.
For electrical wiring and functionality at connection with
Nestor, see separate documentation.
1.1 Energy-saving functions
1.1.1 Control of the supply air temperature/supply
flow temperature
By comparing the supply air temperature downstream of
the fan with the supply flow temperature to the coil, the
equipment makes sure that the valve for the coil opens
only if the water has a temperature that conveys energy to
the air.
This means that if there is a heat load and the water temperature is lower than the supply air temperature, which
can occur during defrosting cycles, the valve is not allowed
to open. If there is a cooling load, the reverse applies.
1.1.2 Optimisation function
A cooling unit/heat pump will be more effective if the difference between the outdoor temperature and the water
temperature is as small as possible. This reduces energy
consumption.
The supply air energy to a water coil is controlled by a
valve. Optimisation of the valve position so that it always
strives to be fully open, and instead control the water
temperature, saves energy.
1.1.3 AQUA Link
The AQUA Link provides both air handling units and
comfort modules with cooling power. Even here energy
savings are obtainable by allowing the need to control the
water temperature.
Depending on whatever the specific need is (dehumidification, cooling of the supply air, cooling of the room via
comfort modules), the temperature of the chilled water
can be varied and the control system ensures that the
chiller will not produce chilled water that is colder than
necessary.
1.1 Installation
The installation work is fast and simple compared with
that of other systems. It requires only hydraulic and electric connection between the GOLD unit, chiller/heat pump
and possible AQUA Link.
All the necessary control functions are ready to activate.

3. Operation
See below and the following pages for diagrammatic
descriptions of the function.
3.1 Control of cooling/heating to the GOLD
via Swegon chiller/heat pump
3.1.1 Chiller
The cooling capacity of the supply air is controlled via an
IQlogic+ module (extra regulation sequence function, see
separate instructions for the TBIQ IQlogic+ module) preset
for cooling (0-10 V). The function can be activated in the
hand-held terminal of the GOLD air handling unit (see the
Operation and Maintenance Instructions for the GOLD).
Communication with the chiller can be activated under
Functions in the hand-held micro terminal of the GOLD
unit. See Section 5.
If temperature sensor BT1 calls for cooling, the function
transmits a refrigerant setpoint (12°C*) to the chiller via
Modbus.
If the temperature by temperature sensor BT50 is lower
than the temperature by temperature sensor BT30**, the
function allows valve MF2 to regulate the flow.
If the temperature by temperature sensor BT50 is higher
than the temperature by temperature sensor BT30**, the
function does not allow valve MF2 to regulate the flow
(forces it to close).
Optimisation function active:
To ensure the best functionality when the optimisation
function is activated, the value for cooling diff. (2 K*)
should be set to the same value as that set in the chiller,
see Section 5.
If the temperature by temperature sensor BT40 (reference
water) is within 2K* from the refrigerant temperature
setpoint and if it has been so during a continuous period
of more than 60 seconds* the optimisation function is
allowed.
If the optimisation function is allowed and valve MF2 is
fully open (100%*) the controller decreases the refrigerant temperature setpoint at a rate of 0.3K/minute*.
If the optimisation function is allowed and valve MF2 is
open less than 80%*, the controller increases the refrigerant temperature setpoint at a rate of 0.6K/minute*.
* Factory setting. The value can be changed.

3.1.2 Heat pump
The heating capacity of the supply air is controlled via an
IQlogic+ module (extra regulation sequence function, see
separate instructions for the TBIQ IQlogic+ module) preset
for heating (0-10 V). The function can be activated in the
hand-held terminal of the GOLD air handling unit (see the
Operation and Maintenance Instructions for the GOLD).
Communication with the heat pump can be activated
under Functions in the hand-held micro terminal of the
GOLD unit. See Section 5.
If temperature sensor BT1 calls for heating, the function
transmits a start signal and heating medium setpoint
(40°C*) to the heat pump via Modbus.
If the temperature by temperature sensor BT50 is higher
than the temperature by temperature sensor BT30**, the
function allows valve MF1 to regulate the flow.
If the temperature by temperature sensor BT50 is lower
than the temperature by temperature sensor BT30**, the
function does not allow valve MF1 to regulate the flow
(forces it to close).
Optimisation function active:
To ensure the best functionality when the optimisation
function is activated, the heating diff. value (3 K*) should
be set to the same value as that set in the heat pump. See
Section 5.
If the temperature by temperature sensor BT40 (reference
water) is within 3K* from the heating medium temperature setpoint and if it has been so during a continuous
period of more than 60 seconds* the optimisation function is allowed.
If the optimisation function is allowed and valve MF1 is
fully open (100%*) the controller increases the heating
medium temperature setpoint at a rate of 0.3K/minute*.
If the optimisation function is allowed and valve MF1 is
open less than 80%*, the controller decreases the refrigerant temperature setpoint at a rate of 0.6K/minute*.
* Factory setting. The value can be changed.

3.1.4 Chiller and external heating
The cooling capacity of the supply air is controlled via an
IQlogic+ module (extra regulation sequence function, see
separate instructions for the TBIQ IQlogic+ module) preset
for cooling (0-10 V). The function can be activated in the
hand-held terminal of the GOLD air handling unit (see the
Operation and Maintenance Instructions for the GOLD).
The function controls external heating (waterborne or
electric) via the GOLD unit’s ordinary output for heating (0-10 V). The air heater for heated water has a frost
monitor function and is automatically activated when it is
connected.
Communication with the chiller can be activated under
Functions in the hand-held micro terminal of the GOLD
unit. See Section 5.
If temperature sensor BT1 calls for cooling, the function
transmits a refrigerant setpoint (12°C*) to the chiller via
Modbus.
If the temperature by temperature sensor BT50 is lower
than the temperature by temperature sensor BT30**, the
function allows valve MF2 to regulate the flow.
If the temperature by temperature sensor BT50 is higher
than the temperature by temperature sensor BT30**, the
function does not allow valve MF2 to regulate the flow
(forces it to close).
If dehumification is active, the function allows valve MF1
to regulate the flow.
Optimisation function active:
To ensure the best functionality when the optimisation
function is activated, the value for cooling diff. (2 K*)
should be set to the same value as that set in the chiller,
see Section 5.
If the temperature by temperature sensor BT40 (reference
water) is within 2K* from the refrigerant temperature
setpoint and if it has been so during a continuous period
of more than 60 seconds* the optimisation function is

fully open (100%*) the controller decreases the refrigerant temperature setpoint at a rate of 0.3K/minute*.
If the optimisation function is allowed and valve MF2 is
open less than 80%*, the controller increases the refrigerant temperature setpoint at a rate of 0.6K/minute*.
