3.11.5 Timer

- The timer block is used to cretate a daily program to
initialise the operation time of the extra output (P3), this
function is generally use for energy saving in the case of an
additional heat source being used to warm the tank (e.g.:
additional heat is present only at the end of the day if the
sun loading was insufficient during the day.)
To use the Timer function select the line "Timer" and choose
"Yes", then there is the possibility of adjusting the "start" and
"stop" times for three blocks.

P3

3.12.1 Cooling start

- setting level to start cooling the tank1 (by activating P3
output) to another heat storage for example when the water
temperature in the top of tank1 (T3) is above this setting
level. (Adjustable 20 to 90°C with factory value 75°C)

3.12.2 Cooling hysteresis

- Value of the hysteresis to stop cooling the tank1 when the
water temperature on the top of tank (T3) is under Cooling
start temperature minus hysteresis value. (Adjustable 1 to
30°C with factory value 10°C)

3.14.1 Start Level
- Setting level on collector (T1) to start the function, the
pump P1 will be turned on to discharge the warm
temperature of the collector through the relay P3.
(Adjustable 0 to 200°C with factory value 110°C)
3.14.2 Stop Level
- Setting level on collector (T1) to stop the antistagnation
function, the pumps P1 and P3 will be turned off. (Adjustable
