<Operation settings>
Heating operation
This function allows operational setting of fl ow temperature range from the Ecodan and also the time interval at which
the FTC collects and processes data for the auto adaptation mode.
1. Heating operation for auto adaptation mode
Menu subtitle
Function
Flow temp. range
Minimum temp.
To minimize the loss by frequent ON and OFF in mild outdoor ambient
temperature seasons.
Maximum temp.
To set max. possible fl ow temperature according to the type of heat emitters. 35 - 60
Room temp. control
Mode
Setting for Room temp. control
At Fast mode, target outlet water temperature is set higher than the one set
at normal mode. This reduces the time to reach the target room temperature
when the room temperature is relatively low.*
Interval
Selectable according to the heat emitter type and the materials of fl oor (i.e.
radiators, fl oor heating-thick, -thin concrete, wood, etc.)
Heat pump thermo diff.adjust
On/Off
To minimize the loss by frequent ON and OFF in mild outdoor ambient-
temperature seasons.
Lower limit
Prohibits heat pump operation until the fl ow temperature drops below the
target fl ow temperature plus lower limit value.
Upper limit
Allows heat pump operation until the fl ow temperature rises above the target
fl ow temperature plus upper limit value.
<Table 5.7.1> Heating operation(Room temp.control table)
Note:
1. The minimum fl ow temperature that prohibits heat pump operation is 20ºC.
2. The maximum fl ow temperature that allows heat pump operation equals to the maximum temperature set in the Flow temp. range
menu.
* Fast mode is not most effi cient and will result in increased running cost when compared to normal mode.
2.Heating operation for auto adaptation, compensation curve, and fl ow temp. control

Function
Flow rate setting
Mode
Auto mode automatically selects a fl ow rate from 3 to 7 L/min appropriate for
effective operation according to Room temp. control. Manual mode targets
Flow rate setting value.
※ Select Manual mode except for Room temp. control.
Flow rate
Select the target circulation fl ow rate for heating at Manual mode.
※ Be aware of the shortage of required fl ow rate for each heat emitters.
Note: Recommended fl ow rate setting at Manual mode is listed below.
• When the Flow temp. is high (e.g. radiator) recommended fl ow rate is low.
• When the Flow temp. is low (e.g. underfl oor heating) recommended fl ow rate is high.
• Low fl ow rate setting with low fl ow temp. may cause frequent ON/OFF operation of pump.
* In case of "Compensation curve mode" or "Flow temp. mode" selected, even if fl ow rate setting is "Auto" mode, fl ow rate will be fi xed at
"7.0 L/min".
Freeze stat function
Menu subtitle
Function/ Description
Freeze stat function
An operational function to prevent the water circuit from freezing when outdoor ambient temperature drops.
Flow t.
The target outlet water temperature at water circuit when operating in Freeze stat function.
Outdoor ambient temp. Minimum outdoor ambient temperature which freeze stat function will begin to operate, (3 - 20ºC) or choose**. If asterisk (**)
is chosen freeze stat function is deactivated. (i.e. primary water freeze risk)"
Note:
1. When the system is turned off, freeze stat function is not enabled.
2. Flow t. is fi xed at 20ºC and unchangeable.

System Set Up
<Energy monitor settings>
In this menu, all parameters required to record the consumed electrical energy and the delivered heat energy which is
displayed on the main controller can be set.The parameters are an electric booster heater capacity, supply power of
water pumps and heat meter pulse.
Follow the procedure described in General Operation for the set up operation.
For Pump 1, *** can be also set besides this setting.
In the case *** is selected, the system acknowledges "factory fi tted pump" is selected.
Default
Refer to the section [Energy Monitor] in "3. Technical Information"

Commissioning
Pre-commissioning exercises- secondary (potable) circuit
Initial fi ll and fl ush procedure:
Ensure all pipe joints and fi ttings are tight and secure.
Open the most distant DHW tap/outlet.
Slowly/gradually open the mains water supply to begin fi lling the secondary (potable) circuit / pipework.
Allow most distant tap to run free and release/purge residual air and any impurities that may have resulted
from the installation work.
Close tap/outlet to retain fully charged system and resume system commissioning.
Commissioning exercises
Energise system to heat-up cylinder unit.
Open the most distant tap and confi rm that hot water is smoothly delivered.
