EKHBRD011~Y1
Indoor unit for air to water heat pump system
4PW60970-1B
Installation manual

status signal (active/not active) from the corresponding
temperature reducing device
Space 0, not using a temperature reducing device (
), always
needs to be linked with the highest water temperature set point and
can be controlled by the remote controller room thermostat function
or by the external room thermostat. Settings for space 0 can be made
on the remote controller (same as during normal operation
(1)
).
The electrical connections on the unit should be done on the optional
demand PCB.
The configuration of pattern B is done by field settings:
1
Select the appropriate pattern: [7-02]=1
2
Turn on multiple set point 1: [7-03]=0
➞
[7-03]=1
Turn on multiple set point 2: [7-04]=0
➞
[7-04]=1
3
Enter the temperature multiple set point 1: [A-03] (see below)
Enter the temperature multiple set point 2: [A-04] (see below)
Configuration example:
Pattern B can also be used to do some primary multi zoning (if all set
point temperatures are selected the same, no temperature reducing
device (
) is required).
Multiple thermo ON signals for 3 rooms can be generated. Thermo
OFF signals are only valid if all requests are OFF.

Classic room thermostat control with remote controller room
thermostat function and external room thermostat
(1) When using the automatic weather dependent function for setting of space 0, you
have to make sure that the lowest possible temperature of the space 0 floating
set point (including the possible negative shift value) is higher than the
temperature set point of spaces 1 and 2.
This means that field setting [3-03] of space 0 needs to be higher than
temperature set point of spaces 1 and 2.

NOTE
■
Leaving water control is not allowed for pattern B.
■
It is the installers responsibility to make sure no
unwanted situations can occur (e.g. too high
water temperatures towards floor heating loops,
etc.).
■
It is the installers responsibility to make sure the
water circuit is well balanced (e.g. when a
domestic hot water request occurs, there will be
sufficient flow towards other appliances as well,
etc.)
■
Daikin does not offer any temperature reducing
device (
). This system only provides the
possibility to use multiple set points.
■
When space 0 is in thermo OFF, but space 1 or 2
are active, space 0 will be fed with water at a
temperature equal to the highest set point of
spaces 1 and 2.
This can lead to unwanted heating of space 0.
