6.1. MANUAL OVERRIDES
A simple rotary switch, shown below, is used to select the override function.
THIS SWITCH CAN BE SET IN ANY MODE INCLUDING REVIEW MODE.
IT IS IMPORTANT TO REMEMBER TO SWITCH BACK TO AUTO AFTER THE
MANUAL OVERRIDE FUNCTION HAS BEEN USED.
WHEN THE SWITCH IS IN AN OVERRIDE CONDITION THE DISPLAY WILL
FLASH AND THE OVERRIDE CONDITION WILL BE INDICATED (EXCEPT IF IT
IS OVERRIDDEN OFF).
PUMP EXERCISE WILL ONLY TAKE PLACE WHEN THE CONTROLLER IS IN
AUTO OR OVERRIDDEN TO STANDBY.
The modes are as follows:
Auto mode: Allows the controller to operate on the time schedule and
uses all of the set parameters.
Day mode: Removes the effect of the time schedule and makes the
controller run at the day set value constantly.
Night mode: This mode overrides the controller time schedule and
decreases the calculated flow temperature by the value
set in night setback.
Boost mode: This mode overrides the controller time schedule and
increases the calculated flow temperature by the value
set in boost.
