Uponor heat only thermostat will show only current room temperature. When 2 buttons are pressed simultaneously the bar shows but does not flash. The floor icon does not show at all. Any ideas?

The Peco TA-170 thermostat is designed to control both heating and cooling, and it appears that it may not allow for separate temperature settings for heating and cooling. However, you can adjust the set point temperature for both heating and cooling modes at the same time by following these steps:

1. Press the "SET" button to enter the programming mode.
2. Use the up and down arrow buttons to adjust the temperature set point. The display will show the current temperature set point for both heating and cooling modes.
3. When you have set the desired temperature, press the "SET" button to save the new set point.

To reset the thermostat to its factory settings, follow these steps:

1. Press and hold the "RESET" button for three seconds.
2. The display will show "RST", indicating that the thermostat is resetting.
3. After a few seconds, the display will go blank and then turn back on, indicating that the reset is complete.

Please keep in mind that resetting the thermostat to its factory settings will erase all programmed settings and return it to its default settings. You will need to reprogram the thermostat to your desired settings after the reset.

Save-Smart®
Press () to activate the Save-Smart®Function.
1.Set the thermostat to desired temperature using the +/-
buttons (Note: The default Save-Smart®temperature is 72 ? F)
2.When you reach the temperature at which you want to
set the unit, the set temperature will flash several times
and then the display will return to indicate the current
room temperature and will gradually change as the
room temperature changes.
3.When the air temperature is less than the set temperature,
the heater will run in HIGH heat.
4.Once the thermostat reaches the set temperature the heater
will automatically switch to LOW heat to save energy.
5.When the air temperature reaches 4? above the set temperature,
the heater will turn off. The Heater will cycle off and on in the LOW
mode to maintain the set temperature.
All this happens automatically with Lasko Save-Smart®Technology.
To deactivate the Save-Smart®function, press Save-Smart®

NOTE: the temperature display does not indicate the temperature of the heated air being emitted by the heater.
3.Once the room temperature reaches 2 degrees above the set temperature, the Heater will shut off. Once the room temperature reaches 1 degree below the set temperature, the Heater will turn back on and continue to cycle off and on to maintain the set temperature.
4.This function will cancel if the ()button is pressed. The Heater will now be in High heat and run continuously.

It sounds like the thermostat is malfunctioning; the Set should not be flashing at all, only the Hld should show after pushing the hold button.
Do you have a new battery in the unit? Is it set to Heat or Cool? Is it already programmed for current Time/Date and does it have a schedule programmed in already? If you've lost the user manual it's here: https://customer.honeywell.com/resources/Techlit/TechLitDocuments/69-0000s/69-1431.pdf

That is a NONprogramable T-stat. There is no program to overide, therefore there is no need for a "hold" option. To set the temp, place the switch on the side marked

COOL
OFF
HEAT

to the desired setting, and push the up down arrows on the front until the display shows 80.

The DISPLAY will revert back to the current room temperature within a few seconds, and will keep the unit on until it reaches the desired temp.

The set temperature remains at 80, it just shows the current room temp.
