Table 25: Hydro Kit Thermostats.
Controller Type
Mechanical (1)
Electrical (2)
1. Thermostat does not have an internal electrical circuit, and a power supply is not required.
2. Thermostat has electric circuits such as display, LED, alarm etc., and a power supply is required.
3. Thermostat displays "Heating ON" or "Heating OFF" signal according to the set heating target temperature.
4. Thermostat displays both "Heating ON" or "Heating OFF" and "Cooling ON" or "Cooling OFF" signal according to set heating and cooling
target temperatures.
Choosing a Heating / Cooling Thermostat
•
• Heating / Cooling Thermostat must feature a manual changeover design and be able to assign separate heating and cooling temperature
setpoints.
If the chosen thermostat does not have both of the features listed above, the Hydro Kit will not operate properly.
• Heating / Cooling Thermostat must be able to send cooling and heating signals immediately when the temperature condition is met. There
can be no delay in trigger timing.
• Some electromechanical thermostats have an internal time delay to protect the compressor. If the chosen electromechanical thermostat
product does not respond quickly.
• The thermostat set temperature range can be different than that of the Hydro Kit and its included controller. Choose heating and cooling set
temperatures to coincide with the set temperature ranges of the Hydro Kit.
•
Doing so will damage the unit control board.
• See the Pre-Commissioning section for function codes and instructions on accessing the Installer mode that will be needed to set up Hydro
Kit accessories.
