Power consumption of G-50A and AN are as follows:

· One G-50A unit = Three AN units

One AN consumes 1/3 as much power as one G-50A.

· One AN unit = Two GR units

One GR, SR, or ST consumes half as much power as an one AN.

(Note 1) Up to 2 central controllers (G-50A) can be connected only when different systems are kept separate.

♦ CAUTION4: Using with a certain combination of multiple system controllers.

● To connect the system controller on the transmission line for central control and be powered from the outdoor unit (Applicable only to R410A compatible models), disconnect the male connector from the female CN41 power supply switch connector, and connect it to the female CN40 power supply switch connector on only one of the outdoor units.

Up to three system controllers (AN/SR/ST/GR) can be connected on the transmission line for central control of the M-NET without the need for a power supply unit for transmission lines.

When the system controller is connected on the transmission line for central control and is powered from the outdoor unit, the number of indoor units that are connectable to each refrigerant system is reduced by 3/1/0.5 unit(s) for each system controller that is connected

5. The ON/OFF Remote Controller can manage up to 50 air-conditioning or ventilation units.

6. One ON/OFF remote controller can control a maximum of 16 groups. The numbering range of the groups that can be managed can be modified using the initial settings but normally the group numbers starting from last two digits of the remote controller’s own address up until a value 15 higher than that can be managed.

(Example) Case where ON/OFF remote controller’s own address is set to

210 Group number: Groups 10 - 25 can be controlled.

In the case where a problem exists with the controlled group range determined by the remote controller’s address setting; By performing the minimum controlled group No. setting in the initial settings described later in the manual, regardless of whether this remote controller has a master setting or subordinate setting, it is possible to set a controlled group range that has no relationship with the setting value of the remote controller’s own address.

For details, refer to 5 Initial Setting .

7. As current consumption is twice that with remote controller when this equipment is connected to the indoor and outdoor transmission wiring, assume two remote controllers for each of these units when calculating connections.

To remove the remote controller cover, gently rotate a slotted screwdriver in the claw points as shown in the right diagram.

CAUTION Press the cover until it snaps shut. If not, it may fall off.

CAUTION

When rotating the driver, gently rotate without applying much force. If too much force is applied, it could break the claw parts.

5 Initial Setting

There are the following two types of initial setting mode.

(A) Minimum controlled group No. setting

The remote controller determines the controlled group range using its own address setting. If the controlled group range that is determined by the remote controller’s own address causes trouble, change the controlled group range by performing the minimum group No. setting.

(B) Group setting

This is used to include the controllers controlled by the remote controller in each group. Indoor units, ventilation units, local remote controllers and slave system controllers are entered in each group.

• When setting a master system controller

It is necessary to perform the group setting. Moreover, it is necessary to perform minimum controlled group No. setting when required.

• When setting a slave system controller

It is necessary to perform minimum controlled group No. setting when required. The group setting is not necessary. The group setting is performed on the master system controller side.

• When interlocking control of a ventilation unit with an indoor unit, the interlocking setting is necessary but it is not set on the remote controller.

Perform the interlocking setting on the local remote controller when this remote controller is set as the master system controller or perform it on the system controller of the master system controller setting when this remote controller is set as the slave system controller.

(If a ON/OFF remote controller is set as the system controller in the master system controller setting, set the interlocking setting on the local remote controller.)

If trouble arises from the controlled group range that was determined by this remote controller’s address, perform the minimum controlled group No. setting regardless of whether this remote controller is set to master setting or slave setting.

(Example) If you want to control exactly the same groups with two ON/OFF remote controllers, it is not possible to duplicate the remote controller address. Therefore the range of the groups that the two ON/OFF remote controllers can control will not match. In such a case, the minimum controlled group No. setting can be modified to determine a controlled group range that is not relative to the remote controller’s own address setting.

(A) Level signal cases

1 In the case where the Emergency stop/Normal signal is selected, when the external input signal contact OFF changes to contact ON,

“Normal” changes to “Emergency stop”. When contact ON changes to contact OFF, “Emergency stop” changes to “Normal”.

2 In the case where the ON/OFF signal is selected, when the external input signal contact OFF changes to contact ON, “OFF” changes to

“ON”, and when contact ON changes to contact OFF, “ON” changes to “OFF”.

(B) Pulse signal cases

1 If the “ON” signal is sent while the equipment is on, the equipment remains on. (The same applies to OFF, Prohibit and Permit.)

2 In the case where local remote controller operation is prohibited, the ON/OFF operations by the local remote controller are prohibited.

3 Set the pulse duration (contact ON period) to 0.5sec or longer.
