Description
D-508F digital non-programmable thermostat is designed to control either
ambient(air) temperature (A Mode) or floor temperature (F Mode) or a
combination of ambient temperature with floor temperature limits(AF Mode). An
auxiliary remote sensor is provided to measure slab temperature in order to
control the floor temperature(within maximum and minimum limits in AF Mode). It
can also be used for sensing the outdoor temperature.

Installation
1. Look for a location which has a constant
temperature in the house and it is no near the
door entry of heater or air conditioning outlet.
The mounting height should be about five feet
above the floor.
2. Insert a screw driver into the slot located on the
right side of the thermostat to open the front
cover.
3. Set the slide switches on the back of the control
module if necessary. Default: AF mode, °F
display.
4. Place base over hole in wall and mark
mounting hole locations on wall using base as
a template.
5. Move base out of the way. Drill mounting holes and use the screws
provided to secure the base. Use plastic anchors if necessary.
6. Through the base opening, connect wires to the terminal blocks on the
base according to Figure 2 below.
7. Carefully line the thermostat up with the base and snap into place.

As soon as the thermostat is powered, all the LCD segments are displayed.
Then it undergoes a series of tests before displaying the actual
temperature.
SETTING THE THERMOSTAT
QuickSet Feature:
Quickset allows the user to change the setpoint temperature instantly without
entering the setting mode. Simply press UP (increase) or Down (decrease)
key during the normal operating mode. When the Up/Down key is pressed, the
setpoint is flashing on the upper right hand corner of the LCD display to indicate
that the setpoint value can be changed. Press the UP/Down key again to
adjust the setpoint (press and hold for auto repeat function). Just walk away
when finish and it will return to normal operating mode after 30 seconds.
Setting Mode:
General Note:
!Press and hold the Up Key or Down Key to change the value continuously
(auto repeat function).
!To return to normal operating mode from the setting mode, press and hold
the SET key for 3 seconds. However, the system also returns to normal
operating mode if no key is pressed for 30 seconds.
!During the setting mode, symbol “SET MODE” is displayed on the upper
left corner of the LCD. Each time SET key is pressed, the data will be saved
into the EEPROM and advance to the next setting(parameter). If no
change of value is required, just press SET key once to go to the next step
(parameter).
Floor Minimum and Maximum limits(AF Mode only)
The thermostat generally turns On or Off to control the ambient temperature.
However, if the floor temperature drops below the set minimum floor
temperature limit, the thermostat will turn heating On regardless of the ambient
temperature. If the floor temperature rises above the maximum limit, the
thermostat will turn heating Off regardless of the ambient temperature to
maintain the floor within the desire limit.
This setting ensures a minimum floor temperature at all times. The maximum
limit is to avoid damage to your floor and for added safety.
Note: The floor minimum limit cannot be set to a higher value than the
maximum limit.

LCD Display
Step 1
To start setting, press the SET key for 3 seconds to access the setpoint mode. The LCD
will display the current setpoint (flashing). Then press either the Up key to increase or
the Down key to decrease the setpoint to the desired setting. An example of LCD
display inAF mode is shown.
Setpoint Temperature
Default setting: 70 F(21 C)
for A or AF mode, 82 F(28 C)
for F mode.

Step 2
Press SET key again to access the differential mode. The LCD will display the current
differential (blinking). Then press either the Up key to increase or the Down key to
decrease the differential to the desired setting. Selection value: 0.5, 1.0, 1.5, 2.0
Differential Temperature
Default setting: 1 F(1 C)° °
Step 3
(A mode only,
otherwise, skip
this step)

Default setting: Auto
View Mode:
Press both Up and Down keys at the same time to review the current control
settings. “VIEW MODE” appears on the upper left corner of the LCD. Then
Press (or Up) key to scroll through the settings in the same order as
Setting Mode (Setpoint, Differential, Heat/Off, Backlit etc.). To exit to normal
mode, press one more time from the last setting (e.g. Backlit) or
press both Up and at the same time. In this mode, the settings
cannot be changed.

Keypad Lock:
Keypad can be locked to prevent tempering by unauthorized personnel. This is
done by pressing SET , Up and Down keys at the same time for three seconds.
A lock symbol appears on the lower LCD screen which indicates that the
keypad is locked. Then input from the keypad is disabled. Press SET, Up and
Down keys at the same time again for another three seconds to unlock the
keypad. The lock symbol disappears from the screen.
Factory setting: unlock
Turning On and Off the Heating System
In the heat mode, the relay is operated to maintain the temperature of the zone.
The control output will turn on when the sensor temperature falls to the setpoint
temperature minus half the differential amount. The control output will turn off as
the temperature rises to the setpoint plus half the differential amount.
During the normal operating mode:
!To disable or enable the relay output, press the power button once(eg. 1
second). LCD indicates a flashing “Heat” or “Off” under the “System”
heading. Press the power button again to toggle between “Heat” to enable
and “Off” to disable the relay output.After 30 seconds, the system returns to
normal operating mode.
!To completely power off the thermostat, press the power button for three
seconds. Press the power button again to turn back on the thermostat.
