Description
The KTD control unit is used to programme and control a solar thermal systems.
Two different versions are available, KTD3 and KTD5, which are used in
combination with R586S, R586S-0 and R586S-1 circulation groups.
The control unit is user-friendly thanks to its backlight graphic display, four
buttons, handy programming assistant and on-line help pages.
The KTD control unit has inputs for temperature probes type Pt1000, a relay
output for controlling an electronic circulator, and one or two relay outputs
for commanding a electronic circulator (predisposition for commanding
circulator by PWM or 0-10 V signal) and one or two relay outputs for other
additional functions.
The programs on the control unit allows to set various system configurations.
Operation control functions range from the mere reading of the current
measured values to long-term system monitoring and analysis by means of
charts and statistics. Numerous other functions complete the possibilities
offered by the KTD control unit:
• at any time, you can reset the previous values or, if necessary, the
manufacturer's default values;
• the menu locking function prevents any unwanted modification of the
operating parameters set during the unit programming phase;
• the anti-lockout function activates the pump or valve connected to the relay
for 5 seconds, at regular intervals, to prevent any possible lockout due to a
lengthy period of non-use;
• the anti-legionella function heats the boiler to a high temperature at fixed
time intervals.
The KTD allows also to view the thermal energy level produced by the solar
thermal system thanks to the setting of certain additional parameters (e.g.
glycol type and percentage, and system flow rate).
