Floor-drying function
The EQJW 125 has two floor-drying functions:
1. Operational heating as per EN 1264, Part 4
EN 1264, Part 4 describes how cement floors should be treated
during operational heating before the floor covering is laid. This
entails, first of all, maintaining an inlet temperature of 25°C for 3 days.
Thereafter, the maximum inlet temperature should be maintained for
four more days, i.e a total of 7 days = 7d. The controller then works in
normal heating mode in accordance with the chosen settings.
2. Screed curing
Screed curing starts with a flow-temperature setpoint of 25°C. This
setpoint is gradually increased – by 5 K a day – until the maximum
flow temperature is reached. The maximum flow temperature is
maintained for 7 days. The setpoint for the flow temperature is then
reduced by 5 K every day until 25°C is reached. The function is then
finished and the controller returns to normal heating mode in
accordance with the chosen settings.
Both functions are called up using SERVice parameter SP60.
1. To perform floor drying in accordance with EN1264 Part 4, the value
7d should be assigned to the parameter.
2. To perform screed curing, a value of 25°C should be assigned to the
parameter.
The EQJW 125 should be adapted to the installation before the floor-drying
function is activated. In particular, SERVice parameter SP19 (maximum flow
temperature) should be set first of all to a suitable value for both the floor and
the heating circuit.
When the floor-drying function is active, the 'house' symbol flashes. An
additional value appears in the display. In the case of operational heating, the
remaining time is shown as follows:
7d = 7 days (at the start), the value counts down to
1d = 1 day
In the case of screed curing, the current phase is shown:
1 = Initialisation,
2 = Temperature build-up phase,
3 = Temperature maintenance phase,
4 = Temperature reduction phase
When the floor-drying function has been successfully completed, the figure 9
appears. If the floor-drying function was interrupted (due to a sensor failure or
high control deviation over a long period etc.), 8 is displayed (instead of 9) as
the error message.
