Possible combinations of indoor units

In general following type of indoor units can be connected to a VRV
IV heat pump system. The list is non-exhaustive and is depending
on both outdoor unit model and indoor unit model combinations.
▪ VRV direct expansion (DX) indoor units (air to air applications).
▪ SA/RA (Sky Air/Residential Air) direct expansion (DX) indoor units
(air to air applications). Further referred to as RA DX indoor units.
▪ Hydrobox (air to water applications): HXY080/125 series only.
▪ AHU (air to air applications): EKEXV-kit+EKEQ-box are required,
depending on application.
▪ Aircurtain (air to air applications): CYQ/CAV (Biddle) series,

INFORMATION
U-series units cannot share the same refrigerant circuit
with T-series units. However, electrically , U-series units
and T-series units can be connected via F1/F2.
▪ RXYQ22~54 consists of 2 or 3 RXYQ8~20 units.
▪ RYYQ22~54 consists of 2 or 3 RYMQ8~20 units.
▪ RYYQ8~20 units cannot be combined.
▪ RYMQ8~20 units cannot be used as standalone outdoor unit.

Cool/heat selector
In order to control the cooling or heating operation from a central
location, the following option can be connected:
Description
Cool/heat changeover switch
Cool/heat changeover PCB
With optional fixing box for the
switch
External control adaptor (DTA104A61/62)
To instruct specific operation with an external input coming from a
central control the external control adaptor can be used. Instructions
(group or individual) can be instructed for low noise operation and
power consumption limitation operation.
PC configurator cable (EKPCCAB)
You can make several commissioning field settings through a
personal computer interface. For this option EKPCCAB is required
which is a dedicated cable to communicate with the outdoor unit.

Heater tape kit
To keep the drain holes free in cold climates with high humidity, you
can install a heater tape kit. If you do so, you also have to install the
heater tape PCB kit.
Description
Heater tape kit for 8~12 HP
Heater tape kit for 14~20 HP
See also: "5.2.2 Additional installation site requirements of the
outdoor unit in cold climates" on
Demand PCB (EKRP1AHTA)
To enable the power saving consumption control by digital inputs
you must install the demand PCB.
For installation instructions, see the installation manual of the
demand PCB and addendum book for optional equipment.
