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.
One supplier of all the equipment.
The IQlogic + module TBIQ-3-1 is included in the AQUA

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.

(40°C*) to the heat pump via Modbus.

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*.

3.2 Control of cooling energy to the GOLD and comfort modules via the Swegon chiller and AQUA Link
3.2.1 Control of cooling energy to the GOLD
The cooling capacity of the supply air is controlled via valve actuator MF2 and an IQlogic+ module (extra regulation sequence function, see separate instructions for the TBIQ
IQlogic+ module) preset for cooling (0-10 V). Cooling can be activated in the hand-held terminal of the GOLD air handling unit (see the Operation and Maintenance Instructions for the GOLD).
3.2.2 Control of cooling energy to the comfort modules
See the function guide for All Year Comfort (AYC).
GOLD
3.2.3 Swegon chiller and AQUA Link
Communication with the chiller can be activated under
Functions in the hand-held micro terminal of the GOLD unit. See Section 5.
Communication with AQUA Link takes place via the
IQlogic + module (function selector switch set to 5) which controls and manages alarms from pump G20. The module is located in the AQUA Links cubicle.
The chiller’s water temperature setpoint is controlled by the GOLD unit and is determined by the cooling load in the ventilation system. The temperature setpoint from the AYC function is compared with the ordinary cooling supply air setpoint and the lowest value of these is transmitted as a setpoint to the chiller.
Circulation pump G20 located inside the AQUA Link is started and stopped via the GOLD unit. When the GOLD unit is in operation and valve MF2 or MF10 is open more than 5%, circulation pump G20 starts up.
Optimisation function active:
Applies to the supply air cooling setpoint.
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*.
