Honeywell Line Voltage Thermostat Problem

This is a Honeywell RLV310A line voltage thermostat connected to one eight foot 240v baseboard heater. I've tried 2 of these in the same location and have encountered the exact same issue. The thermostat registeres the correct temperature in the room until heat is called for. Then the temperature registered by the thermostat actually goes down instead of up. And it just continues to draw heat (indefinitley I guess). As I said I've tried 2 of them and they do the same thing. Once I manually adjust the setting on the thermostat down, it again registers the correct temperature. Any ideas as to what is going on? Hard to believe both of them were defective.
One thing to note, this thermostat is mounted directly next to a Lux low voltage thermostat that controls my radiant floor heat. The electric heat is for backup.
Thanks.

The thermostat cannot be used with the following:
a resistive load under 2 A
systems driven by a contactor or a relay (inductive load)
fan-equipped heating systems
central heating systems
Do you have a contactor or relay connected to the stat?

No, it's connected directly to 1 eight foot long 240 v baseboard heater, which I believe would be 2000 watts, 8 amps.
