5.3.2 Possible options for the outdoor unit

Mounting stand (EKMST1, EKMST2)

In colder regions where heavy snowfall can occur, it is recommended to install the
outdoor unit on a mounting frame. Use one of the following models:

EKMST1  with  flange  feet:  to  install  the  outdoor  unit  on  a  concrete  foundation
where drilling is allowed.

EKMST2  with  rubber  feet:  to  install  the  outdoor  unit  on  foundations  where
drilling is not allowed or possible, such as flat roofs or pavements.

For installation instructions, see the installation manual of the mounting stand.

5.3.3 Possible options for the indoor unit

Multi-zoning wired controls

You can connect the following multi-zoning wired controls:

Multi-zoning base unit 230 V (EKWUFHTA1V3)

Digital thermostat 230 V (EKWCTRDI1V3)

Analogue thermostat 230 V (EKWCTRAN1V3)

Actuator 230 V (EKWCVATR1V3)

For  installation  instructions,  see  the  installation  manual  of  the  control,  and  the
addendum book for optional equipment.

Room thermostat (EKRTWA, EKRTR1, EKRTRB)

You can connect an optional room thermostat to the indoor unit. This thermostat
can either be wired (EKRTWA) or wireless (EKRTR1, EKRTRB).

For  installation  instructions,  see  the  installation  manual  of  the  room  thermostat
and addendum book for optional equipment.

Remote sensor for wireless thermostat (EKRTETS)

You can use the remote indoor temperature sensor (EKRTETS) only in combination
with the wireless thermostat (EKRTR1 or EKRTRB).

For  installation  instructions,  see  the  installation  manual  of  the  room  thermostat
and the addendum book for optional equipment.

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.
