We have two issues. I suspect that they are not actually problems – the heating work fine.


Worcester Greenstar CDi. Installed in unheated garage. Protected by Honeywell pipestat and froststat.


1. The garage was cold (approx. 7° C). The room thermostat had demanded heating and the house had reached the set point (15°C) and the thermostat opened. The thermostat was turned up to 19°C. The boiler and pump switched on. The temperature on the display fell as the cooler water in the radiators was pumped back into the boiler. At 28°C the boiler switched off for 30 seconds (green ignition light went off, pump and boiler fan still running) and then flared on again and heated the water up to 64°C At all times, the roomstat was closed, demanding heating.


2. The garage was cold (approx. 7° C). There was no demand from the room thermostat or Hot water. The boiler temperature was approx. 60°C. The boiler ignited (green light on) for 30 seconds and the fan in the boiler ran for two minutes. It then switched off.


The heating does what is meant to – keep the house warm, but do was have an underlying problem? There was no faults shown on the boiler display and I cannot envisage any scenario that explains these actions. Please can anyone throw any light on it?
 
Frost stat set to #5 Boiler must of initiated the temperature being close enough 7 degs a bit close to BRRR +or- at the actual temp
When its cold and temperature reached boiler will function to prevent any freezing occurring.
Yes when Green lights out - no flames present at chamber - pump keeps running dissipating to check all moving parts connected to the system are working correctly also reserving a temperature status somewhere within the system
also if room stat was "CLOSED" - this is a demand for HEATING ON ..! OFF as opposed to being OPEN!
CLOSED - ON
OPEN - OFF
