Pc Interface; Test Programs - Daikin EKOMB22AAV1 Installation Instructions Manual

The control system ensures the tap water temperature is correct. The water
temperature can be set between 40°C and 65°C (see par. 7.1). The set tap water
temperature is displayed on the operation panel. The standard setting is 60°C.
You can press the service button during tap water operation to read the actual tap water
temperature.
7 Heating up unit
In order to provide a fast supply of domestic hot water, a so-called tap comfort function
has been installed in the unit. This function keeps the heat exchanger at the right
temperature (this temperature can be set, see par. 7.2). The tap comfort function has
the following settings:
On: (
LED on) The tap comfort function of the unit is continuously switched on.
•
The unit always immediately provides warm water.
Eco: ( LED on) The tap comfort function of the unit is self-learning. The unit will
•
adjust to the usage pattern of the domestic hot water. This means the heat
exchanger will not be kept warm during the night or during longer absences.
Off: (Both LEDs off) The heat exchanger is not kept warm which means the supply of
•
domestic hot water takes a bit of time. If there is no need for fast delivery of domestic
hot water, the tap comfort function can be switched off.

PC Interface

The boiler controller is provided with an interface for a PC. A PC can be connected by
means of a special dongle, and the associated software. This facility enables you to
follow the behavior of the boiler controller, the unit and the heat installation over a long
period.

2.5.1 Frost protection
The unit is fitted with frost protection in order to prevent it from
•
freezing. If the temperature of the heat exchanger drops too low, the
pump will start running until the temperature of the heat exchanger
is sufficiently high. If the frost protection intervenes, code
displayed (heating up exchanger).
If the installation (or a part thereof) can freeze, the coldest place
•
should be fitted with an (external) frost thermostat on the return pipe.
This must be connected in accordance with the electrical diagram
(see par. 10.1).
Note
-
When the unit is switched off ( on the service display), the unit frost protection will
remain active, however a heating request from an (external) frost thermostat will be
ignored.
