5.5.7 Circulation pump for storage tank charging (CO2 F04)

This function can be selected for systems 2

and 3.

The circulation pump CP is switched off when

the storage charging pump SCP is activated

(factory setting). After switching off the stor-

age charging pump SCP, the circulation

pump CP operates according to the defined

time schedule. If you select CO2 F04-1, how-

ever, the circulation pump continues to oper-

ate in parallel with the storage charging

pump.

5.5.8 Parallel pump operation (CO2 F06)

Select this function for systems 2 and 3.

Should the total available capacity be suffi-

ciently high to operate both the heating sys-

tem and charge the drinking water storage

tank, you can configure the controller for par-

allel pump operation. Select CO2 F06 -1,

and for system 2 additionally select: 1 (paral-

lel pump operation). The heating circulation

pump then continues to operate during the

storage tank charging as long as the charg-

ing temperature does not exceed the current

set point for the heating circuit by more than

10 K and the max. permissible flow tempera-

ture is not exceeded. If the system deviation

of the charging temperature is higher than 5

K after the adjusted time Waiting time until

HCP off (default 600 sec), the heating circu-

lation pump is switched off for 10 minutes.

5.5.9 Thermal disinfection of drinking water storage tank (CO2 F05)

This function can be selected for systems 2

and 3, if one or two storage tank sensors are

configured. In conjunction with a storage

tank thermostat (CO2 F01-0), thermal disin-

fection cannot be used. On the configuration

level CO2, therefore, function block F01-1

must be set for one storage tank sensor, or

function blocks F01-1 and F02-1 must be set

for two storage tank sensors.

Activate thermal disinfection with CO2

F05-1. It protects the drinking water in the

storage tank from excessive contamination

with legionella. For this purpose, the drinking

water is strongly heated up. The day of the

week, the storage tank set point, the start

time and the stop time for this process can be

selected after you have activated the thermal

disinfection function (function block parame-

ter). Factory setting is for the thermal disin-

fection to start Wednesdays at 0:00 (mid-

night), with a storage tank set point of 70

and to end at the very latest at 4:00 (a.m.),

even when the set point in the drinking water

storage tank has not been reached yet.
