HVAC SYSTEMS AND MANUAL

This is a technical discussion of the heating and cooling system in the house.
Maintenance for these systems is the responsibility of the Tenant. Maintenance work must be performed in the spring and the fall with detailed receipts sent to the Landlord or Landlord’s agent.

RHEEM GAS HEATERS – TWINNED DUAL

These were installed new in 2013 and replaced a pre-war gas furnace.

Heat should be supplied PRIMARILY by the device designed for that purpose, namely the RHEEM Gas heaters located in the basement and venting through all of the rooms. HVAC Units, if used at all for heat, should be used only in the AUTO system. It will take a good hour for these to start working and blowing hot air.

 

Suggested settings are from 68 to 72 degrees and always on HEAT and fan always on AUTO.
I would program the Ecobee thermostat to lower the temp to 68 at night and on weekends and 72 on the weekdays during 9am to 5pm. You can make small changes to it after that to perfect the comfort. The temperature differential should only be about 4 degrees from night to day. It is your responsibility to control the thermostat to your liking.

 

The Thermostat is an Ecobee that allows remote control.
The manual is available at ecobee.com

 

FUJITSU HEAT PUMP AND AIR CONDITIONING UNITS

We have 13 Fujitsu HVAC heat pumps at the home. These were installed as new in 2008. Originally there were 14 but one of these (back 4th floor) was removed when the partition wall between the back bedrooms was removed to make one large bedroom. The spare unit is in the basement.

 

Heat from these is SECONDARY. Use the gas furnace for PRIMARY heating.

ALL UNITS MUST BE SET TO EITHER COOL OR HEAT – do not mix modes
Heat pumps do not work very well when it is cold. It can takeĀ almost two hours to get up to temperature when it was cold.

To produce heat the Fujitsu heat pump systems must have their FAN set to AUTO. If you set a system to another setting you probably get just the FAN.

I can make available a copy of the manual on request.
From page EN-16
“During Heating operation, the unit will temporarily stop operation (between 7 and 15 minutes) as the Automatic Defrosting mode operates. During the Automatic Defrosting operation, the OPERATION indicator lamp will flash.”Please read the manual on page EN-17 regarding auto defrost, EN-18 about the limits of the system in cold weather.
EN-8 will tell you how to set the system to turn on automatically before arriving at work.

1) Each unit has its own system controller. They allow programming and several different settings. The most helpful is the auto-off function so that the units will run only while you are in the room.

2) General heat for the house should be provided by the main system. Not the heat pumps which should be used only for modifying certain room temperatures.

3) The outside condensers should be kept unblocked and free of leaves and other debris. Snow removal around the exterior heat pumps is very important.
