Hello everybody

I'm doing a simulation for a heating floor system and cooling floor system.

To make this system, first I have assigned the Internal construction source on the floor of my building, after in the thermal zone I have assigned to each zone a ZoneHVAC: Low Temperature Radiant: variable Flow assigning schedules thermostat, both winter and summer and fractional Schedules of operation in the equipment.

After I’ve done two circuits Empty plant loop, one for the cooling circuit and other for the heating circuit assigning the Zone HVAC: Low Temperature Radiant: Variable Flow to the corresponding circuit, these circuits are formed to: variable pump + bolier/chiller and bypass piper + piper +piper+ Low Temperature Radiant: variable Flow + piper.

In the set point manager of these circuits I have assigned the water outlet temperature, being these 15 degrees for the cooling and 35 degrees for the heating circuit with a tolerance of ± 1 degree this.

The problem is, how to go to the open result viewer is able to see that the temperature inside the building does not follow the set point thermostats, and the value of the power consumed in the open result viewer gives zero I would appreciate any help or advice to solve my problem and apologize for my low level English.

LowTemperatureRadiant uses a setpoint schedule other than the thermal zone thermostat, have you checked/assigned that?

if I created two different schedules for the floor heating system and I have assigned this schedules in the zone equipment: low temp variable flow, doing this does not follow the set point thermostats

Radiant objects will not follow zone thermostats. They set their control based of the schedule defined in the Heating Control Temperature Schedule Name field or Cooling Control Temperature Schedule Name field.

Forgiveness is possible you have not explained well, the new schedules I have created, I have assigned in Heating Control Temperature Schedule Name field and Cooling Control Temperature Schedule Name field but the temperature don't follow tihs schedules
