(4) Control of the heater temperature
1
Room thermostat detects the room temperature while the heater thermostat monitors the heater
temperature.
2
The room thermostat temperature determines the heater control temperature. (The colder the room
temperature, the heater control temperature becomes higher, and the hot air temperature is maintained at
about 35°C.)
3
Heater turns ON/OFF depending on the heater control temperature, but it does not turn ON in the following
occasions.
• When the heater switch is turned “OFF” (Heater lamp is extinguished.)
• When the jet towel is operating
• When the room thermostat detection temperature is 35°C or higher
(5) Extinguishing of the illumination lamp
1 If the jumper wire (JA) on the indicator circuit board (JT-24S-A) is cut off, the illumination lamp extinguishes.
2
Before cutting off the jumper wire, make sure to turn the power switch “OFF” and wait for 40 seconds
minimum.
(6) Test mode (Error display mode)
1
Content .….….….….Display the latest error occurred.
When no error is retained in the memory, the power lamp flickers quickly.
There is no other indication than the above. (Operation is inhibited.)
2
Setting method ….…In the condition that a resistor of 4.7k Ω is connected between pins 1 and 2 of CN8 on
the main circuit board, turn “ON” the power switch.
3
Resetting method …Turn “OFF” the power switch. After waiting for more than 40 seconds, remove the
above resistor.
