Anti-Legionella (Pasteurisation) Function - Lochinvar EcoForce EF80 Installation, Commissioning, User And Maintenance Instructions

NTI EGIONELLA
To prevent Legionnaires' disease, the water heater (software) provides a function for heating up the hot water storage tank (once a week or
every day) to a higher water temperature than the normal active hot water set point. Also the period, that this "higher" water temperature
function must be active, can be programmed in P7BV start time (0:00) and P7BW (8) and is standard switched off.
Also an external 0-10Vdc signal can be used to activate the pasteurisation function this can be done by making the 0-10V signal higher than
10,2V.
The standard factory setting for this pasteurisation function is "OFF". To activate this' function some parameters must
be programmed by a trained service engineer. The starting day and starting time of this function can be programmed
by the control panel of the water heater and by using a computer, interface cable and the water heater software.
Several parameters are used for this function. Three of these parameters are shown in the following graph.
P5CI = 5°C
This is the bandwith within which the Legionnaires'
temperature must stay during the programmed
duration time period. In this example the temperature
is allowed to fluctuate between 65°C and 70°C during
the anti Legionnaires' function.
Normal setting
water temperature.
Start of the anti Legionnaires'
disease program (start day and
time can be programmed).
Values for illustration purposes, programmed parameter values can deviate!
The settings of these parameters P5CI, P5CJ and P5CD must be programmed according to local regulations and requirements for the site.
The setting of these parameters can only be done by a trained service engineer and is also possible by the control panel of the unit without
the use of a computer.
The use and activation of this function cannot guarantee a Legionnaires' free installation. A suitable risk
assessment and regular monitoring should be in place

ASTEURISATION UNCTION
P5CJ = 80 min.
This is the duration within which the water
temperature must be between the 65°C and 70°C.
Time (10 min steps)
P5CD = 70 °C
This is the maximum temperature during anti
Legionnaires' disease function period.
