Mount the main controller MC-230, IOT-L2-2 linker, PM1-E-D, PM3-E-D and PM3-I-D power sensors, fuses, power relays, and push-buttons to a suitable location.

Wire all elements except communication with PM1-E-D and PM3-E-D sensors.

Connect the MC-230 and IOT-L2-2 to the home LAN or use LTE 4G modem.

The power plants can be connected to the grid in two ways:

serial with grid power sensor		parallel with grid power sensor

When configuring the power plant, select

• in: serial (internal) with grid power sensor
• ex: parallel (external) with grid power sensor

The power plants are configured as internal by default.

Enable the wireless setting to add, delete, or set repeater level of wireless modules.

• Launch the pairing by the press on the learning button on the back of the device.
• The wireless sensor is added in the HEMS Configurator.

• Launch the pairing by the press on the button for 2 seconds until the LED becomes red. Release the button, the LED will then glow in red
• To confirm that the pairing is OK, the LED will blink in green
• In the HEMS Configurator module should appear as a “new device”
• Click on the “ add” button next to the consumer that is connected to the module

• Launch the pairing by doing 3 consecutive presses on the relay switch button. The LED blinks red
• To confirm that the pairing is OK, the LED will blink green twice
• The HEMS Configurator module should appear as a “new device”
• Click on the “ add” button next to the consumer that is connected to the module

• Launch the pairing by doing 3 consecutive presses on the relay switch button. The LED blinks red
• To confirm that the pairing is OK, the LED will blink green twice
• In the HEMS Configurator the module first channel should appear as a “new device”
• Click on the “ add” button next to the consumer that is connected to the modules first channel
• In the HEMS Configurator the module second channel should appear as a “new device”
• Click on the “ add” button next to the consumer that is connected to the modules second channel
• Before you pair a new device both channels must be added to the consumers

• In the HEMS Configurator press “del” button next to the consumer connected to the module you want to remove
• After a few seconds the module is removed

• In the HEMS Configurator press “del” button next to the consumer connected to the channel module you want to remove
• After a few seconds, deleted channel of a module should appear as a “new device”
• We can remove the module by deleting the second channel or the deleted channel can be assigned to another consumer

When enabling repeater mode, the wireless module can repeat a message not addressed to him, and increase range by creating network between all wireless devices.

The repeater can be configured to level 0 (off), level 1 (one hop), or level 2 (two hops):

• Level 0: gateway — module.
• Level 1: gateway — repeater — module.
• Level 2: gateway — repeater — repeater — module¹.

By default, the repeater mode is disabled (level 0). If you want to change the repeater mode press icon «» in the output in Consumers settings table.

¹ Both repeaters must be set to level 2.

For each consumer we can set:

• sub: mark device as a submeter if device is not part of internal network and/or is not connected as intended by default. Energy division for this device will be ignored.
• man. time: the time is in minutes for the manual override. It serves to ensure that the user can ensure a minimum validity of the manual switchover.
• timetable checkbox: enable or disable the timetable for each device.

HEMS will automatically detect compatible

• battery systems eStore and
• home automation systems HIQ Home

which are in the same local network.

Only the first system is detected, if there is more than one it is necessary to enter the NAD number of the desired system manually.

if eStore is enabled, HEMS will read:

• grid power-sensor
• power-sensor for the first PV Plant and
• power-sensor of the first storage system

From the enabled HIQ Home system, HEMS will automatically read the grid power-sensor.

HEMS is connected to the internet via IOT-L2-2 linker.

HEMS is supporting up to 8 digital outputs on MC controller (QX0,QX1,QX2,QX3,IO12,IO13,IO14 and IO15). How to set?

• using HEMS configurator on settings page, define digital output for desired consumer (e.g. Digital-2),
• on IO MUX page assign digital to output port (e.g. IO15 → Digital 2): in this case consumer 2 (Digital-2) is assigned to IO15 port and enables ON/OFF functionality on it.

Note: if it is set digital for consumer without assigned power sensor, it is possible to define P nominal power instead. It represents fixed power of consumer and while in operating mode HEMS calculates consumed energy.

On port IO14 is supported analog output 0-10V, while on IO15 is PWM signal with frequency of 1kHz. Using analog load is possible for consumer 1 only! How to set (HEMS wiring)?

• using HEMS configurator on settings page, define analog output for consumer 1,
• on IO MUX page define IO14 and/or IO15 port for Analog/PWM output,
• on home screen define analog value 0-100% (long-press) for consumer1 and turn it ON/OFF with short-press.

Note: if it is set analog for consumer without assigned power sensor, it is possible to define P nominal power instead. It represents fixed power of consumer and while in operating mode HEMS calculates consumed energy.

IO mux page within HEMS configurator allows setting of input/output types for ports on controller:

• e.g. if it is set QX2 → Router reset, it means that when conditions are met (for reset), QX2 port will change state to turn OFF router,
• or if it is set QX2 → Digital-2, it means that digital2 (consumer 2) is assigned to QX2 and enables switching ON/OFF on it,
• for input ports IX0,IX1 and IX2 it is possible to set toggle and enable functionality (HEMS wiring). it means that dedicated consumer will be directly managed (ON/OFF) by input signal on IX0,IX1 or IX2.

Saving parameters to the permanent memory, after changing the settings, is necessary since at startup HEMS always reads parameters from the permanent memory.

HEMS Configurator allows you to backup and restores all parameters to PC.

Under limiter page set correct phase order to align phases of each device. Set correct main fuse limit [A] to protect the main grid fuse from over current. Check devices that can be managed by limiter and set correct limiter priority. Choose from no limiter, limit last, limit second, limit first. Max expected device current consumption is dynamically calculated and does not need to be set. In case device is an EV charging station, manually set max current for this device.
