• HTTP option part number is DCM007A51

• HTTP option should be purchased and activated like the BACnet Client, BACnet Server and PPD options.

• Allows the BMS to monitor and control the VRV indoor unit through HTTP protocol.

• The BMS will be able to monitor and control the following items:

• Normal/ Error monitor

• ON/OFF

• Operation Mode

• Setpoint

• Room Temp

• Fan speed

• Louver direction

• Ventilation mode

• Ventilation amount

Schedule Update

Add outdoor unit to the ITM

▪ AirNet address should be assigned to the ODU using outdoor field settings (2-13) or using the remote remote controller

▪ An outdoor unit can be added to the iTM as a management data point with an AirNet address.

▪ Enable ODU demand control using ODU field settings (2-12)

▪ Assign a demand address to the ODU using ODU field settings (2-02)


Schedule Update

Schedule function improvement:

Added VRV Outdoor Unit capacity suppression and low noise to the schedule function of iTM.

Example:

A project is requiring:

1- A low noise control schedule from 12 to 4 am to meet a city low noise ordinance during the specified time.

2- ODU capacity reduction schedule for 70% from 1 pm to 5 pm to avoid a higher utility rate (Critical Peak Pricing) during the afternoon hours.

3rd Party

Controller Up to 7 adaptors

Demand Control

Di4

▪ Power Limit Control (Demand Control) is intended to reduce power consumption when a 3rd party demand controller sends demand control signals to the iTM.

▪ Demand signals can be interlocked with the iTM or the iTM plus adaptor digital inputs.

▪ The following demand control strategies can be executed by the iTM

▪ Indoor unit setpoint shift control

▪ Indoor unit thermo on/off control

▪ Outdoor unit capacity control

▪ 3rd party equipment (lighting) On/Off control with the use of WAGO DO module.

▪ iTM support up to 3 demand control signals

▪ A facility manager can use the iTM web function to configure or disable the demand control remotely.

Demand Control

How demand control works?

▪ The below table shows the load cut-off levels corresponding to the iTM Di inputs


Demand Control

Example of switching to a higher level Example of switching to a lower level

Once an input signal

turns on, demand

control switches to

the corresponding

load cut off level

Demand Control doesn’t switch to a lower

load cut off level for 5 min. after turning on. (if

the level 3 signal turns off withing 5 min. after

turning on, the load cut off level remains at 3

without changing to 0

5min. After the input

signal turns on, the

load cut off level

changes to a lower

level (5 min. later,

only the level 2 is

on. Therefore, the

load cut off level

changes to 2)


Demand Control

Three different control strategies

Indoor Unit Settings Temp Control

Outdoor Unit Capacity Control

Indoor Unit Thermo On/Off Control

▪ Decide on the demand control strategy based on the project requirement.

▪ Avoid applying demand control to critical zones like server rooms


Demand Control

Indoor Unit Settings Temp Control

Setpoint shift based on the configured levels from the current setpoint.

▪ Up to 128 indoor units can be assigned per group

▪ Up to 8 control groups

▪ It is not possible to register one unit (management point) in more than one groups.

▪ Configured cooling setpoint upper limit and heating setpoint lower limit.

▪ Example:

▪ If the indoor unit is in cooling 72F and level 2 signal is activated, the cooling setpoint will be shifted to 74F

▪ If level 3 signal is activated, the cooling setpoint will be shifted to 76F (2F setpoint shift)

▪ When the signal is released, the cooling setpoint will go back to 72F(4F setpoint shift)

4

Note: Cut-off Level 3 should be always the highest level of energy saving.


Demand Control

• A group of outdoor units can be assigned to capacity limit control logic

• Outdoor unit capacity can be configured for 0, 40, 70,100% when the digital input signal activated.

• Multiple levels of reduced capacity can be applied

• Example:

• When the level 2 signal is activated, the ODU capacity will be reduced to 40%.

Outdoor Unit Capacity Control

Note: • Cut-off Level 3 should be always the highest level of energy saving.

• Outdoor unit capacity control is only applicable for VRV system.


Demand Control

• A group of indoor units can be assigned to the demand signal level for the thermo on/off control.

• Example:

• When the demand control signal for level 1 is activated, the indoor units in the group control A will be forced thermo-off.

• The remote controller will display “S” icon (Energy Saving)

Indoor Unit Thermo On/Off Control

Note: Cut-off Level 3 should be always the highest level of energy saving.
