Kit for bathroom towel radiators
(electric heating element and TZT 63 electronic plug-in thermostat)
User Guide
Description
Bathroom towel radiators connected to a traditional hydronic heating system
can be fitted with a kit for dual heating that contains an electric heating
element, TZT 63 thermostat, and a T-piece. In this case, the heating fluid is
heated up either by the electric heating element only, or also from the
central heating circuit using the T-piece supplied. The heating element gets
wired via the plug-in room thermostat where the desired temperature is set.
Bathroom towel radiators with dual heating can be placed in zones 2 and 3
(next to a wash basin, bathtub, or shower cabin).
A comfortable heating element can be obtained by simply installing of
recommended heating element into a radiator.

Operation
The plug-in thermostat controls the temperature for the local heater; it shows
either the set temperature or the measured one.
Description and adjustment of the thermostat mode
The thermostat TZT 63 turns on as soon as plugged in, ”On” and 20 °C
temperature appears on the display. After a while, the real temperature is
measured and kept displayed.
In this mode, the thermostat switches the heating on and off in such a way
that the room temperature reaches the set value (the factory preset value is
20 °C).
Setting another temperature: press the up or down key, and the timer time
starts flashing. Press OK (c-1 and the preset temperature starts flashing. It
can be modified by pressing the up or down key, in the range from 5 to 35
°C in 0.5 °C increments. Press OK ( ). to save the value. The LCD returns to
displaying “On” and the ambient temperature.
Description and adjustment of the timer mode
Switching from the thermostat mode to the timer mode is done by pressing OK (
). The remaining time is displayed on the LCD together with a flame symbol
(heating on). The countdown starts running, indicated by a flashing colon in
the remaining time (factory preset value is 2:00 hours). After a short delay,
the thermostat will switch the heating on. This is indicated by the lit green
LED. The heating is turned on regardless of the ambient and preset
temperatures.
Setting another timer value: press the up or down key, and the timer time
starts flashing. The desired timer value can be set by pressing the up or down
key between 15 min. and 5 hours, in 15 min. steps. Then press OK ( ).
After one more pressing ( ) the display will show the timer and the flame
symbol again (heating on). The preset timer value will be modified in case the
appliance is the thermostat mode. When in timer mode, the timer value will be
updated only after pressing twice the key OK ( ). Countdown starts. When the
preset time expires, timer mode ends and the appliance returns to the
thermostat mode. The display shows “On” and the ambient temperature again.
Note: Temperature and countdown time can be changed from
either thermostat mode or timer mode. After pressing OK ( ) the appliance will
return to the mode preceding pressing the up or down key. If during the
thermostat adjustment no key is pressed for 10 sec., the appliance will return
to the mode preceding pressing up or down.
Warning: In case of a power supply interruption the modified values will
be lost and the factory values set as default
Temperature Control
- Switching heating on Heating is switched on (the thermostat closed) if the ambient temperature is 0.5°C lower than the set temperature.
- Switching heating off: The heating is switched off (the thermostat is open) if the ambient temperature is 0.5°C higher than the set temperature.
- If the ambient temperature falls below 5°C, the frost protection mode is activated and heating switched on regardless of the desired temperature. The frost mode is indicated by the symbol
This electric heating element is equipped with an automatic thermal reset at
90 °C that will release again automatically when cooled down to 35 °C. The
element is also equipped with a safety cutoff that turns it off permanently
when the temperature exceeds 110 °C.
The kit for bathroom towel radiators also contains a T-piece that is needed
for dual heating (when the radiator is a part of a heating circuit and also
heated by a heating element if necessary).
