2.0 Installation

2.1 Description, in general

Application keys for the ECL Comfort 210 / 296 / 310 series, which control heating circuits, offer a floor drying program, also called screed drying program.

The floor drying program is used after a new floor heating circuit has been placed and fresh-from-factory concrete covers the floor heating pipes. The floor drying program can also be used, when the self-leveling screed has been distributed.

The floor drying program can be started immediately in order to dry-out the concrete / screed according to a set time / temperature plan.

Navigation to the menu for ‘Floor drying’:
Common controller > MENU > Floor drying:

Functional heating:       The flow temperature is controlled according to a set time / temperature plan in order to dry-out the concrete / screed.

Curing heating:             The flow temperature is controlled according to a set time / temperature plan in order to cure the concrete / screed. The curing must be done before mounting of, for example, tiles.

Functional and curing heating can work as one process or separated.

The time / temperature plan is set and is common for selected circuits.

T           = Time

1 #    = Functional heating

2 #    = Curing heating

When the floor drying process is finished, a data log can be read from the ECL Comfort controller by means of the “ECL Tool”. The data log can be used for documenting the process.

The favorite display with temperature information of the heating circuit(s) can, as an example, look like this:

Floor drying process not active:

Floor drying process active:
The progress bar is filled up from left side, according to time elapsed since process start. The elapsed time and total process time is also indicated in hours.
Return temperature related indications are not present, as the return temperature limitation is cancelled during the floor drying process.

Floor drying process being active can also be seen:
Circuit x > MENU > Influence overview > Des. flow T:

Before start of the floor drying process:

• The control parameters must be set correctly (Circuit x > MENU > Settings > Control parameters). See the Operating Guide for the application in question.
• The Time & Date must be set correctly (Common controller > MENU > Time & Date). See the Operating Guide for the application in question. The Time & Date settings are used in the log facilities.

The mode selector of the ECL Comfort controller must not be in Manual mode when the floor drying process is in progress.

3.0 Settings

3.1 Parameters and descriptions

Parameter tables contain parameter name, ID and descriptions.

Parameters’ setting range and factory settings are listed in the section “Parameter ID overview” at the end of this Operating Guide.

Desired flow T (Desired flow temperature)          Read-out

Read-out of the desired flow temperature.

– – – :      The floor drying process is not active

Value:    The floor drying process is active

Push the dial to:

• select / deselect circuit(s) for floor drying
• enter / change the graph of the “Functional heating” or “Curing heating” process

The desired flow temperature can be set at:

• X1, X2, X3 and X4 (Functional heating)
• X5, X6, X7 and X8 (Curing heating)

Selection of circuit(s) for floor drying:

1 2        Circuit number selected
1 2        Circuit number not selected

Important: The desired flow temperature values, set at X4 and X8 are used as controlling temperatures:

• after the floor drying process, if the application is not to be started
• after a power failure

Examples of graph:

Times for X1, X2, X3 and X4 are the same (0 h)
Desired temperature at X1 is 20 °C
Desired temperature at X2 is 20 °C
Desired temperature at X3 is 20 °C
Desired temperature at X4 is 20 °C

Times for X1, X2, X3 and X4 are different, as shown.
Desired temperature at X1 is 20 °C
Desired temperature at X2 is 50 °C
Desired temperature at X3 is 50 °C
Desired temperature at X4 is 20 °C

Application with one heating circuit:
If the floor drying process is in operation and the circuit, by accident, is changed not to be selected, the floor drying process must be restarted.

Application with two or three heating circuits:
If the floor drying process is in operation for two or three circuits and one of the circuits, by accident, is changed not to be selected, the floor drying process continues. Just select the circuit in question again.

Prog. execution (Program execution)                       10512

Start or stop the floor drying process.
Press and hold the dial for 5 seconds in order to start or stop the process.

OFF:    The floor drying process is not active

ON:     The floor drying process is active

If the ECL Comfort controller is set to manual mode, the floor drying process can be started, but will not be active.

If “Prog. execution” is set to ON and returns to OFF after 5 seconds, none of the circuits in the graph (Desired flow T) have been selected for floor drying.

If the parameter “Appl. continue” (ID 10912) is set to STOP, the “Prog. execution” remains ON after elapse of the floor drying process.

Max. pwr. failure (Max. power failure period acceptance)   10514

Setting the max. accepted time for power failure.
If the ECL Comfort controller is without power for more than the set time, the alarm will be activated when the controller is powered up.

Value: Set the accepted time

The alarm can be reset (MENU > Alarm > Alarm overview)

To restart the floor drying process:
If the parameter “After power fail.” (ID 10913) is set to STOP, the “Prog. execution” must be set to OFF and then to ON.

After a power failure, the alarm is indicated / activated.
If the parameter “After power fail.” (ID 10913) is set to STOP, the desired flow temperature is maintained at the value, set in X1.

Ramp X5 – X6 (Temperature ramping from time X5 to X6)    10903
Ramp X7 – X8 (Temperature ramping from time X7 to X8)    10904

Setting the number of steps for the change of the desired flow temperature in selected period.

OFF:     The stepwise change is disabled

Value:    The period is divided in the number of steps

Example:
“X5” time is set to 100
“X5” temperature is set to 25 °C

“X6” time is set to 150
“X6” temperature is set to 35 °C

“Ramp X5 – X6” is set to 5

Result:
Period between X5 and X6 is 50 hours. Temperature change is 10 K.
The process will be:
Start temperature: 25 °C, after 10 hours the temperature changes to 27 °C. After further 10 hours the temperature changes to 29 °C and so on.

Appl. continue (Application continue)                   10912

Selection how the ECL Comfort controller must continue after having finished the floor drying process.

OFF:    The desired flow temperature will be the value set at “X8” time

ON:      The controller continues with the selected application and the set mode of the function selector

When using only “Functional heating” and no demand for control after the floor drying process, it is important to set the desired temperature at X8.
(Common controller > MENU > Floor drying > Curing heating > “Desired flow T” > Graph’s right point).

After power fail. (After power failure)                      10913

Selection how the ECL Comfort controller must continue after a power failure (power has been away for more than accepted time, set in “Max. pwr. failure”, ID 10514).

If power failure happens in “Functional heating” process, the floor drying can be restarted according to time and temperature setting for X1 or stopped. If stopped, the desired flow temperature is maintained at the value, set for X1.

If power failure happens in “Curing heating” process, the floor drying can be restarted according to time and temperature setting for X4. If stopped the desired flow temperature is maintained at the value, set for X1.

STOP:      The controller stops the floor drying process and maintains the temperature, set at X1

START:    The controller starts the floor drying process from settings in X1 or X4

To restart the floor drying process:
If the parameter “After power fail.” (ID 10913) is set to STOP, the “Prog. execution” must be set to OFF and then to ON.

After a power failure, the alarm is indicated.
The alarm can be reset.

X1 (Start time for period 1)                                  10930
X2 (Start time for period 2)                                  10931
X3 (Start time for period 3)                                  10932
X4 (Start time for period 4)                                  10933

The time that must elapse from process start for controlling the set flow temperature in the functional heating period.

Values:   Set the times

Example 1:

X1   =   50 hours
X2   =   50 hours
X3   =   200 hours
X4   =   200 hours

Result:
The desired flow temperature, which will be maintained from process start, is the value, which is indicated / set at X1 in “Desired flow T”.
50 hours after process start, the desired flow temperature, which is indicated / set at X2 in “Desired flow T”, will be maintained.
200 hours after process start, the desired flow temperature, which is indicated / set at X3 in “Desired flow T”, will be maintained.
200 hours after process start, the desired flow temperature, which is indicated / set at X4 in “Desired flow T”, will be maintained.

Example 2:

X1   =   50 hours
X2   =   100 hours
X3   =   150 hours
X4   =   200 hours

Result:
The desired flow temperature, which will be maintained from process start, is the value, which is indicated / set at X1 in “Desired flow T”.
50 hours after process start, the desired flow temperature will gradually rise / fall to the value, which is indicated / set at X2 in “Desired flow T”.
150 hours after process start, the desired flow temperature will gradually rise / fall to the value, which is indicated / set at X3 in “Desired flow T”.
200 hours after process start, the desired flow temperature will gradually rise / fall to the value, which is indicated / set at X4 in “Desired flow T”.

If the functional heating period should not be used, X4 can be set 0 h (zero hours).

X5 (Start time for period 5)                                  10934
X6 (Start time for period 6)                                  10935
X7 (Start time for period 7)                                  10936
X8 (Start time for period 8)                                  10937

The time that must elapse from time X4 for controlling the set flow temperature in the curing heating period

Values:   Set the times

If the temperature values, set at X4 and X5, are different, the desired flow temperature changes gradually from the X4 value to the X5 value.

When X5 is set to a time value, the desired flow temperature starts with the value, set at X4.

If the curing heating period should not be used, X8 can be set 0 h (zero hours).
