Example 3
The week schedule for the building is set with comfort periods
Monday - Friday: 07.00 - 17.30. Sometimes, a team meeting takes
place in the evening or in the week-end.
An override switch is installed and heating must be ON (Comfort
mode) as long as the switch is ON.
Choose an unused input, for example S8. Connect the override
switch.
Settings in ECL:
1. Select circuit > MENU > Settings > Application > Ext. input:
Select the input S8 (the wiring example)
2. Select circuit > MENU > Settings > Application > Ext. mode:
Select COMFORT
3. Remember to set the circuit in question in scheduled mode
("clock").
Result: When the override switch (or a relay contact) is ON, the ECL
210 / 296 / 310 will operate in Comfort mode.
When the override switch is OFF, the ECL 210 / 296 / 310 will
operate according to the schedule.
# 1 # = Override switch (not activated / activated)
# 2 # = Function mode (Schedule / Comfort)
# 3 # = Time
Example 4
The week schedule for the building is set with comfort periods all
weekdays: 06.00 - 20.00. Sometimes, the desired flow temperature
must be constant on 65 °C.
An override relay is installed and the flow temperature must be
65 °C as long as the override relay is activated.
Choose an unused input, for example S8. Connect the contacts of
the override relay.
Settings in ECL:
1. Select circuit > MENU > Settings > Application > Ext. input:
Select the input S8 (the wiring example)
2. Select circuit > MENU > Settings > Application > Ext. mode:
Select CONST. T
3. Select circuit > MENU > Settings > Flow temperature >
Desired T (ID 1x004):
Set to 65 °C
4. Remember to set the circuit in question in scheduled mode
("clock").
Result: When the override relay is activated, the ECL 210 / 296 / 310
will operate in Const. temp. mode and control a flow temperature
of 65 °C.
When the override relay is not activated, the ECL 210 / 296 / 310
will operate according to the schedule.
# 1 # = Override switch (not activated / activated)
# 2 # = Function mode (Schedule / Const. temp.)
