When the optimisation function is switched off (SP53 = 0), the heating is also
switched off initially on changing from normal to reduced mode if the room
temperature is at least 2.5 K higher than the setpoint for reduced mode. Not
until the room temperature has fallen back to the setpoint does the heating
mode start again in accordance with the heating characteristic. If, due to
extraneous heat, the room temperature again rises by more than 2.5 K above
the setpoint, the heating switches off again.
Floor drying
The EQJW 145 has two floor-drying functions:
1. Functional heating in accordance with EN 1264 Part 4. This describes
how cement floors must be treated before floor coverings are laid.
Firstly, a flow temperature of 25°C must be maintained over 3 days for
this purpose. After this, the maximum flow temperature should be
maintained for 4 more days (i.e. a total of 7 days = 7 d). The controller
then works in normal heating mode in accordance with the settings
chosen.
2. Ready-for-laying heating
This involves starting with a flow-temperature setpoint of 25°C. The
flow-temperature setpoint is gradually increased by 5K a day until the
maximum flow temperature has been attained. The maximum flow
temperature is then maintained for 7 days, after which the flow-
temperature setpoint is gradually reduced by 5K every day until a
temperature of 25°C has been reached. The function is then finished
and control is again effected in normal heating mode in accordance
with the chosen settings.
You can call both of these functions up with the help of SERVice
parameter SP60. To perform functional heating in accordance with EN
1264 Part 4, a value of
7d must be assigned to the parameter. To
perform ready-for-laying heating, the parameter should have a value
of
25°C assigned to it.
The EQJW 145 should be adapted to the installation before floor drying is
enabled. Parameter SP22 (maximum flow temperature) in particular should
first be set to an appropriate value for the floor and the heating circuit.
When the floor drying function is active, the flashing 'house' symbol is
displayed. An additional value appears in the display.
If functional heating is activated, the remaining time is shown, e.g. 7d = 7
days (at the start), counting down to 1d = 1 day.
