Taconova - TACOCONTROL Z1 S

Frost protection

Anti-lock protection

Remote off

Keep warm function

If the supply temperature is approaching freezing point, the control

is activated. The circulation pump starts and the valve makes adjust-

ments to set a minimum setpoint. When the supply temperature rea-

ches 8 °C, the control continues operating for a number of minutes

before switching off again. This prevents water from freezing in the

pipes.

If the pump does not operate for several days, then the pump is

briefly moved without opening the valve. This prevents the pump from

locking up mechanically.

There is the option of equipping the controller circuit board with

remote off. Remote off also overrides manual mode and frost protec-

tion. The shutoff function is inactive, which is why the contact on the

corresponding terminals is open.

A valve in the primary supply keeps the supply line to the unit warm

for fast hot water preparation. The keep warm function keeps the

supply line at a temperature between the parameter settings for ON

level KWF and Off level KWF.

Only basic values are available in the HMI if no log-in as service

personnel has occurred by entering the corresponding PIN. The log-in

procedure and the description of potential additional settings and

functions are listed in a separate appendix for the service personnel.

The controller can continually record measured data

and parameters (e.g. domestic hot water flow rate).

This function can be deactivated by the service

personnel by using the instructions in the corre-

sponding appendix.
