The SMMS DX Interface is designed to allow the connection of a third party air handling unit (with R410A DX Coil) to a Toshiba VRF outdoor unit (MiNi-SMMS / SMMS / SMMS-i / SHRM).

The Interface consists of a DX Controller, and a DX VALVE KIT (3 sizes). This is a kit of parts which the installer needs to assemble (including brazing).

3 INSTALLATION

Cooling & Heating output figures are based on calculations and ‘general’ test data. All figures are to be taken as approximations. The properties of the DX coils (by others) will have an affect on the performance of the outdoor units. All capacity data shown in this brochure is based on the following conditions : - Cooling : indoor air temperature 27°C db / 19°C wb, outdoor air temperature 35°C db Heating : indoor air temperature 20°C db, outdoor air temperature 7°C db / 6°C wb

NOTES If the wiring is properly carried out by a specialist according to the local regulations, the device fulfills the protection class IP65. Diversity Ratio: Maximum 110% (When a DX Interface is connected) The MiNi-SMMS cannot be connected to MM-DXV280. Cooling Mode Coil “Air On” Temp : Minimum 15°CWB / Maximum 24°CWB Air temperatures flowing across the coil below this level, can in some circumstances, cause icing and freezing issues with the coil and eventually forcing the system to shut down and also be detrimental to the outdoor unit itself. Heating Mode Coil “Air On” Temp : Minimum 15°CDB / Maximum 28°CDB In the reverse cycle mode when the outdoor unit is producing hot gas, the coil in the AHU is effectively the condenser. Air temperatures flowing across the coil below this level, can cause over condensing of the refrigerant. This can result in liquid being returned to the compressor which will cause a mechanical failure of the outdoor unit. Low air temperatures will also cause the unit to use it's defrost mode more often. Fresh Air Intake If you wish to use Fresh Air which is outside of these Coil “Air On” limits it has to either be pre-conditioned by other equipment, or mixed with return air (or a combination of both) so that it remains inside these limits, in order to ensure reliable operation. Automatic Mode Please be aware that frequent mode changes could occur when using Automatic mode (SHRM).

PIPING SCHEMATIC

Notes: 1) The PMV must be water cooled whilst brazing, to prevent damage to the mechanism. 2) The TCJ Sensor Holder must be brazed to the capillary on the DX Coil’s lowest circuit. 3) For brazing, be sure to use nitrogen gas to avoid oxidation of pipe inner surface.

The DX controller must not be installed outside. To avoid damage, when making holes for cables glands, please first remove the Gland Plate from the DX controller. To maintain waterproof integrity IP65 glands must be used through the gland plate.

DX COIL PREPARATION

The DX Valve Kit is supplied as separate components. These will need to be assembled and then fitted to DX Coil. This is a custom process as each DX Coil will be different, time and care should be given to this activity, and it should be prepared off-site. Note that the PMV body MUST be water cooled whilst brazing. For brazing, be sure to use nitrogen gas to avoid oxidation of pipe inner surface. Typically the DX Coil will have a Gas Header, and a Liquid Capillary Distributor (see below):-

TC1 Sensor Ø4 (Small Sensor Holder). 1 x Braze. Gas Header Pipe.

TCJ Sensor Ø6 (Large Sensor Holder). 1 x Braze. This should be brazed to the lowest Distributor Pipe.

PMV Body, 2 x Strainer, TC2 Sensor Ø6 (Large Sensor Holder). Custom local Pipes. 8 x Braze. Below Distributor.

SENSOR HOLDERS

Sensor Holders MUST be brazed on to the DX Coil pipe work to ensure reliable temperature sensing. There are three coil sensors, these are inserted into the Sensor Holders, and secured with the sensor-fix-plate. The sensor holders should be brazed at the 6’oclock position.

It is essential that the sensors are correctly located to ensure efficient system performance.

TA SENSOR

Secure this sensor using the supplied plastic clamp. It must be located in the Return Air Flow (Prior to mixing with any fresh air). Ensure that the Resin Sensor bulb is not covered by the protective vinyl-tube.

5-EN

Avoid positioning Sensor holders in the Drain Pan where they could be immersed in water.

MM-DXV080 DX VALVE KIT

The PMV for this model is supplied as a brazed assembly, you may need to de-braze this in order to match the piping configuration of your DX Coil.

DX VALVE KIT

The supplied components need to be assembled on to the DX Coil locally. Note the PMV body MUST be water cooled whilst brazing.

The PMV Body must be installed upright (as shown).

The flow through the PMV Body can be in either direction, however the TC2 sensor must be fitted on the distributor side.

ELECTRICAL CONNECTION Pulse modulation valve (PMV) The connecting cable of the PMV is to be attached as follows: Terminal 81 WHITE Terminal 82 YELLOW Terminal 83 GREEN Terminal 84 BLUE Terminal 85 BLACK Terminal 86 RED The PMV cable can be extended with a 6-core cable (cross-section 0.75 mm²) to a maximum of 5 m. Temperature sensors The refrigerant temperature sensors are inserted into the brazed sensor holders (There are 2 sizes of refrigerant Sensors: Ø4 & Ø6) and secured using the supplied FIX-PLATE (There are 2 sizes of FIX-PLATE). The sensor cables are to be attached as follows: Terminal 50/51 TC1 Sensor Ø4 Terminal 52/53 TC2 Sensor Ø6 Terminal 54/55 TCJ Sensor Ø6 Terminal 56/57 TA Resin Bulb Sensor (P-CLAMP) The sensor cables can be extended with a 2-core cable (cross-section 0.75 mm²) to a maximum of 5 m. External safety contact Terminal 9/10 If this contact is open for more than 1 minute, the error message P10 is generated and the ventilation kit switches off automatically. This contact can, for instance, be used with an onsite frost protection monitor. Inside device BUS line (U1/U2) Terminal U1 / U2 Details regarding the wiring of the inside device BUS can be found in the installation manual of the S-MMS outside device. Remote control BUS line (A/B) Terminal A / B At these terminals an optional remote temperature sensor (TCB-TC21LE2) can be attached. Additionally one of either a second wired remote control or alternatively the RBC-FDP3-PE BMS accessory can be optionally attached. Note that you cannot have both a second remote control and the BMS accessory. External release (optional) Terminal 1/2 On/off over an external dry contact. If the contact is closed, the system switches on. If the contact is opened, the system switches off. If the system is switched using and external contact, then switching on/off using the remote control is still possible. Operation monitor Terminal 3/4 An operation monitor (supplied locally), of the external fan is to be attached at this terminal as a dry contact (for instance, differential pressure monitor, vane relay or similar). A closed contact generates the error message L30. Alarm signal from the ventilation kit (optional) Terminal 5/6 If there is an error at the ventilation kit, this is indicated with a dry normally open contact at this terminal. Operation notification from the ventilation kit (optional) Terminal 7/8 During operation of the ventilation kit the dry contact between 7/8 is closed. Supply Terminal L/N/PE The controller should be connected to the main power supply by means of a switch with a contact separation of at least 3mm.

If the External safety contact is not used, then the contact should be bridged.
