Heating Systems

Diagnosing Heating Problems

Overview

The heating systems for the buildings are 2 separate systems.  Each unit consists of:


Battery Failures:


Heating Not Working (radiators not heating) Checks:

  1. Thermostat has batteries - if they are dead then no heat will be called from the boiler
  2. Days and time are correct on the thermostat.
  3. Demand Heat icon is illuminated on the thermostat (little flame).
  4. Controller is set to “ALL DAY”.
  5. Boiler is switched on and illuminated with “call”
  6. Pump is operational (test using a screw driver by placing this on the pump casing and placing the other end of the screw driver to your ear – a humming noise will indicate the pump is operational). The pump will only operate if the heating has be called from the thermostat.
  7. Radiator valves are set to 2 ½


Still not working:

Under Mezzanine - Heat Control

Set Up:

The Electric Boiler is on permanently (unless switched off in the summer) but not always producing hot water, this is controlled by the thermostat.

Timer/Controller is set to permanently "on" - 

Thermostat - this controls the on/off of the boiler to produce hot water for the radiators under the following circumstances:

1.  Too hot - switches boiler off

2.  Too cold - switches the boiler off

3.  Time of day to switch off

4.  Time of day to switch on

5. Days to switch on

6.  Days to switch off.

 

PROGRAMMING THE THERMOSTAT

To control when the area is to be heated the Thermostat must be programmed.
