The Green Zone and Heat Pump Fossil Fuel applications

The following only applies when you are using a Z-300-HPS or Z-600 and the dipswitch is set to "FOSSIL". This will NOT work if the dipswitch on our zone board is set to conventional.

Typically we tell contractors when using our Z-300-HPS or Z-600 for fossil fuel applications that the thermostats should be set up as conventional heat pump thermostats (heat pump with electric auxiliary heat). This might be the simplest thing to do; however it is not absolutely necessary to set the thermostats up this way. The thermostats can be set up for heat pump stats with fossil fuel backup and the zone board should work fine. Also, when setting up thermostats such as the VisionPRO 8000 or the IAQ you have the option in the advanced installer menu to select "external fossil fuel kit controls backup heat" or "thermostat controls backup heat". You can choose either option and the zone board should work fine.

We still recommend setting the stats up as conventional heat pump thermostats (heat pump with electric auxiliary) for simplicity and consistency.

Copper theft is increasing with the copper prices – again

As many of you know, copper prices have continued to rise. As we have seen before, when copper prices are up, so is copper theft. If copper theft is a problem in your area, please consider protecting your investment with a Warning Watchdog, the complete condensing unit protection security system. The Warning Watchdogcan protect up to 4 split systems or RTU’s with one control panel.

Below is a link to an article describing the theft issues in Michigan.

VisionPRO IAQ and desert humidification

This application will not come up often in the Midwest but it is good for everyone to be aware of for special applications that require a call for humidity during a call for cooling by a VisionPRO IAQ.

When using a TrueSteam (or any other humidifier) with a VisionPRO IAQthere is an advanced installer setup function in the VisionPRO IAQ called Desert Humidification. Desert Humidification allows you to call for humidity when you are in the cooling mode. If you do not select desert humidification you can only call for humidity in the heating or off mode.

If you select desert humidification in the advance installer menu, you MUST have a discharge air sensor (part # C7835A1009) for this function to work. The discharge air sensor monitors the dew point temperature to prevent condensation in the duct work. The discharge air sensor is connected to the VisionPRO IAQ Equipment Interface Module.

Jackson Systems stocks the discharge air senor #C7835A1009

Controlling Dual Fuel without an Outdoor Temperature Sensor

White Rodgers Heat Pump 90 Series thermostats use a temperature control algorithm to determine the optimum time to activate the second stage or auxiliary heat.  The thermostat constantly monitors 1st stage performance and produces a time delay based on the result.  The time element of the delay (0-30 minutes) varies depending on the performance of the first stage.  As an example, in Heating, assume for the last 2 hours the thermostat is set on 70° and the room temperature is 70° with the equipment using only the first stage of heat.  The thermostat calculates (internally) the performance of the system.  Since the equipment is keeping the temperature within 1° of setpoint, the thermostat will delay second stage for a longer time if the room temperature quickly changes.  Once the second stage comes on, it will come on sooner the next time there is a difference between the setpoint and the room temperature.  The thermostat is constantly monitoring the performance of the system and the systems ability to keep the area within about 1 degree of setpoint so even raising the temperature in heating or lowering it in cooling will not always force the thermostat to bring the second stage on quickly.  The net effect of the staging program is when the first stage is capable of making temperature the second stage will delay longer.  When the thermostat calculates that first stage cannot make temperature in a reasonable time, the second stage will come on sooner.  This is a built in function that automatically optimizes the use of additional stages of heat or cool.  A thermostat on a Dual Fuel system uses a staging algorithm like the one described above and also turns off the compressor(s) when the furnace is energized.

It is not possible to change the algorithm to prevent the thermostat from staging but staging is always based on performance.
