Using Temma 2 Driver for new coordinate

We are sending commands to indiserver that is connected to Temma 2 telescope as a client.
We are able to move and stop moving the telescope using the following commands:
<newSwitchVector device="Temma" name="TELESCOPE_MOTION_NS"> <oneSwitch name="MOTION_SOUTH">On</oneSwitch> </newSwitchVector>
<newSwitchVector device="Temma" name="TELESCOPE_MOTION_NS"> <oneSwitch name="MOTION_SOUTH">Off</oneSwitch> </newSwitchVector>
etc. for North, West, East

But we cannot set the coordinates to move the telescope using RA and DEC(in TRACK mode), or to synch the coordinates(in SYNC mode) using the commands:
<newNumberVector device="Temma" name="EQUATORIAL_EOD_COORD"> <oneNumber name="RA">00:00:00</oneNumber> <oneNumber name="DEC">10:00:00</oneNumber> </newNumberVector>
Sometimes it shows the following error, but sometimes it times out without the message:
<message device="Temma" timestamp="2018-11-21T17:08:19" message="[ERROR] SendCommand: Timeout error"/>
while the same commands work for the "Telescope Simulator".

We can not really see what is wrong but we suspect it is related to the geographical location and LST time not set. Are they related? Right now we are trying to go through the c++ code from indi github for Temma driver to get some clues, but it is not going well.
LAT and LONG in geographical location can be set easily; however, the TIME_UTC is in format of "text" and we cannot successfully set it. Is this time the one we need to change or not?
properties for TIME_UTC:
<defTextVector device="Temma" name="TIME_UTC" label="UTC" group="Site Management" state="Idle" perm="rw" timeout="60" timestamp="2018-11-21T18:13:13">
    <defText name="UTC" label="UTC Time"/>
    <defText name="OFFSET" label="UTC Offset"/>
</defTextVector>

please help.
