Dual thermostat for servo mixing valve

pozsothereal commented 2 years ago

Hi, first thx for your good work, i would use it with a servo like mixing valve to control the primary water temp of my floor heating. It needs to be a dual climate with both heating and cooling switch unit, for turning the servo cw and ccw. Now i done this by 2 climate with altered temp of -0.1°C on one of them, and using a helper automation to keep one switch off for sure when heating/cooling is in on state. Thx in advance!

id: floor_water_temp alias: floor_water_temp trigger:
- platform: state entity_id: 'input_text.floor_water_temp' action:
- service: climate.set_temperature data_template: entity_id: climate.floor_heating_water_thermostat_decreasing temperature: "{{ states('input_text.floor_water_temp') }}"
- service: climate.set_temperature data_template: entity_id: climate.floor_heating_water_thermostat_increasing temperature: "{{ states('input_text.floor_water_temp') | float - 0.1 }}"
id: floor_relay_control_1 alias: relay controller 1 trigger:
- platform: state entity_id: 'input_boolean.floor_water_decreasing' from: 'off' to: 'on' action:
- service: input_boolean.turn_off data: entity_id: 'input_boolean.floor_water_increasing'
id: floor_relay_control_2 alias: relay controller 2 trigger:
- platform: state entity_id: 'input_boolean.floor_water_increasing' from: 'off' to: 'on' action:
- service: input_boolean.turn_off data: entity_id: 'input_boolean.floor_water_decreasing'

Hi and thank you! I was looking for a way to control a motor managing my shunt-valve for my heating system and stumbled upon this. I am already using the integration to control some floorheating-actuators successfully. Could you please elaborate how you ensure that both of the outputs are never active simultaneously? You are talking about a helper automation, how do you implement it?

pozsothereal commented 2 years ago

Hi, the section started from 'id: floor_relay_control_1' is the exclusion automation to help keep only one climate output active at the same time.

mocklarn commented 2 years ago

Sorry, when i am looking at it now it is clear. I was mistaken it for the connection between the thermostat and the output, but i guess that configuration is placed somewhere else in your configuration.yaml.

I was also thinking about the PWM-periods. Are all thermostat PWM periods starting at the same time (as long as the period length is the same)? I guess otherwise it can be problem. Assuming that the the temperature is correct, the period of the thermostats are 10 seconds and the servo is first closing 5 sec and then opening 5 sec instead of just standing still for 10 seconds?

Regarding your exclusion, simple and elegant! Think I will use it in my coming control of my shunt-motor. Thank you!

No problem, btw my conf looks like this, the waiting period is manageable with the right pwm, cycle time and k values i think, try to start with this;)

Thank you for the guidance @pozsothereal, it was very helpful! It took me some time to understand that it was helpers You were using since i haven´t used such before. I have not tested the configuration to manipulate the motor but the "click" and indicated states of my relay is telling me that it is working as intended.

Hi,

Happy to help you!

Hello, I don't understand what is your issue ? Should this be changed to a discussion instead ?

pozsothereal commented 1 year ago

Hi, yes sure we can, the point is to have both switch in one climate.

Like this: heater: switch.study_heater cooler: switch.study_cooler
