(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.
