THERMO- SAFETY FEATURE – RECEIVER (T/S –RX)
This SKYTECH remote control has a THERMO-SAFETY feature that is built into the system’s RECEIVER. This feature is
temperature- activated and provides an extra margin of safety when the RECEIVER is operating where ambient
temperatures exceed 130°F degrees inside the receiver case.
The THERMO-SAFETY feature, in the RECEIVER, operates in the following manner, when the appliance is in operation.
The receiver is thermally protected from extreme heat conditions. Heat can have negative effect on the operation of the
receiver’s microprocessors.
For REMOTE RECEIVERS that operate on BATTERY POWER, these heat conditions can cause batteries to discharge
when temperatures exceed 115°F. Studies show that alkaline batteries, when exposed to a constant temperature of
115°F, can lose up to 50% of their operating power. When the battery cools down, it will partially recharge itself, but
constant heating and cooling will reduce the battery’s normal life expectancy.
When the ambient temperature at the THERMISTOR, inside the receiver case, reaches 130°F, the THERMISTOR will
automatically shut the appliance down and the RECEIVER will begin emitting a series of 3 “beeps”, every 4 seconds.
When the ambient temperature, at the RECEIVER, drops between 120°F and 130°F, the user can reactivate the appliance
by pushing the MODE button on the transmitter. The word ON must display on the LCD screen. When the MODE button
is pressed to ON, the THERMISTOR “resets” itself and the replace will begin operating again. However, the “beep-
ing” will continue, if the ambient temperature remains between 120°F and 130°F. This “beeping” alerts the user that the
RECEIVER should be repositioned so the ambient temperature drops below 120°F.
When the temperature drops below 120°F, the “beeping” will cease, providing the user has “reset” the THERMISTOR by
pushing the MODE button OFF then ON to operate the appliance. Allow sufcient time for the receiver to cool below
120°F, and then press MODE button to stop beeping.
TRANSMITTER
TRANSMITTER OPERATING DISTANCE
The SKYTECH remote control operates on RF (radio frequency) signals that are sent by the TRANSMITTER (remote)
to the RECEIVER that operates the appliance. It is recommended that the TRANSMITTER always be located within the
20-foot operating range, preferably in the same room in which the appliance is located.
THERMO UPDATING FEATURE –TRANSMITTER
This SKYTECH remote control has a THERMO UPDATING Feature built into its software. The THERMO UPDATING
Feature operates in the following manner, but only in the THERMO and PROGRAM modes.
The transmitter normally reads the ROOM temperature every 2 minutes; checking the ROOM temperature against the
SET temperature by sending a signal to the receiver.
GENERAL INFORMATION CONTINUED
COMMUNICATION – SAFETY – TRANSMITTER – (C/S – TX)
This SKYTECH series remote controls have a COMMUNICATION – SAFETY function built into the software. It provides
an extra margin of safety when the TRANSMITTER is out of the normal 20-foot operating range of the receiver.
The COMMUNICATION – SAFETY feature operates in the following manner for all OPERATING MODES: ON/THERMO/
OFF.
At all times and in all OPERATING MODES, the transmitter sends an RF signal every fteen (15) minutes, to the receiver,
indicating that the transmitter is within the normal operating range of 20-feet. Should the receiver NOT receive a
transmitter signal every 15 minutes, the IC software, in the RECEIVER will begin a 2-HOUR (120-minute) countdown
timing function. If during this 2-hour period, the receiver does not receive a signal from the transmitter, the receiver will
shut down the replace being controlled by the receiver. The RECEIVER will then emit a series of rapid “beeps” for a
period of 10 seconds. Then after 10 seconds of rapid beeping, the RECEIVER will continue to emit a single “beep” every
4 seconds until a transmitter signal is again received. The intermittent 4-second beeping will go on for as long as the
receiver’s batteries last which could be in excess of one year.
