Daikin EWAQ021BAW - External Room Thermostat Option; Option Setup

ESIE11-05 Remote Controller
Functional Description 93
8.2.7 [6] Option Setup
 [6-01] External room thermostat option
If the optional external room thermostat is installed (option EKRP1AHT*), its operation must
be enabled by field setting. Default [6-01]=0, which means no external room thermostat is
installed. Set [6-01] to 1 or 2 if the optional external room thermostat is installed.
The two possibilities as field settings are:
 [6-01]=1
Room thermostat input 1 = heating operation ON/OFF
(*1)
Room thermostat input 2 = cooling operation ON/OFF
(*2)
 [6-01]=2
Room thermostat input 1 = thermo ON/OFF
(*1)
Room thermostat input 2 = cooling (0)/heating (1) selection
(*2)
The external room thermostat only gives an ON/OFF signal to the unit. So it can not be
controlled for example with a signal from 4-20 mA. To have a good control of the system and
avoid frequent ON/OFF, it is advised to use the automatic weather dependent set point
operation.
(*1)
this is the connection 1-5 on option EKRP1AHT see wiring for more information.
(*2)
this is the connection 2-5 on option EKRP1AHT see wiring for more information.
For the control of the system and avoiding frequent ON/OFF it is advised to use the
automatic weather dependent set point operation.
 [6-03] This setting is only applicable for units that need a setpoint below 0°C. A negative
setpoint can not directly be set on the remote controller. This is done threw field settings:
 [A-04] must be set to 1 “glycol concentration setting” (see page 95 for more information)
 [6-03] negative setpoint: here you must fill in your desired negative setpoint.
Furthermore this negative setpoint will only be accepted, when the LWT setpoint on the
remote controller is set to 0°C.
To be able to put LWT setpoint on 0°C you need to change [C-03] to 0 (only possible for
EW*Q*BAW*B* units).
Example: for setpoint of -5°C set [A-04]=1, [C-03]=0, [6-03]=-5 and remote controller LWT
setpoint 0°C.
8.2.8 [7] Option Setup
 [7-00] Forced pump operation.
 [7-00]=0 the pump performs intermittent sampling during thermo off conditions. This
setting is often used when the unit is controlled by a room thermostat.
 [7-00]=1 the pump continues operation during thermo off conditions (default).
