My water furnace thermostat is saying call service

Customer Question
My water furnace thermostat...

My water furnace thermostat is saying call service technician and then under that it says system on heat pump plus two is flashing what does that mean we have no heat in our house

Contractor's Assistant: Did you double-check the thermostat's settings? And what about the filters?

I have an inline water filter that I cleaned and I change the air filter and I'm still blowing out Ice Cold Air and after the thermostat runs for about 5 minutes then that c service technic***** *****ght starts blinking again still no heat just cold air coming out of the register

Contractor's Assistant: Do you plan on doing the work yourself?

I am an electrical contractor and familiar with the electrical side I have changed the computer board in the past and the external solenoid that turns on and off a water valve so yes I will if I can

Contractor's Assistant: Anything else we should know to help you best?

The only light only furnace that is blinking is the green status LED light which I understand means that all systems are working properly so I don't know what to do next 4
