Have you read the node-red-contrib-ramp-thermostat readme?
It say's;

This node expects a numeric msg.payload containing the current temperature (number). The msg.topic should be set to setCurrent

You are injecting a 'string' msg.payload instead of a 'number'. ALSO the message topic is something like "/espDHT11terary/DHT11/Temp" instead of either setCurrent (or undefined).

The node will probably accept the msg.payload because although a 'string', it takes the form of a number, but the topic MUST be either setCurrent or 'undefined'.

Try adding this in front of the node-red-contrib-ramp-thermostat node.
