Group rows when using case expresion - sql-server

Question

I have the folloring query, that give me the next result:
select OBJ_POSITION,
CASE
WHEN (EVT_JOBTYPE = 'PM' and EVT_DESC like '%TMPL%') THEN (SUM(CONVERT(float, ACT_EST)))
ELSE '0'
END as HORAS_TMPL,
CASE
WHEN (EVT_JOBTYPE = 'CMS') THEN (SUM(CONVERT(float, ACT_EST)))
ELSE '0'
END as HORAS_SUST,
CASE
WHEN ((EVT_JOBTYPE = 'PM' and EVT_DESC like '%TMPL%') or (EVT_JOBTYPE = 'CMS')) THEN (SUM(CONVERT(float, ACT_EST)))
ELSE '0'
END as TOTAL_HORAS
from R5ACTIVITIES inner join R5EVENTS on ACT_EVENT = EVT_CODE inner join R5OBJECTS on EVT_OBJECT = OBJ_CODE
where OBJ_ORG = '156' and OBJ_POSITION like '156-EBM%' and EVT_STATUS = 'R' and EVT_TYPE in ('JOB', 'PPM')
group by OBJ_POSITION, EVT_JOBTYPE, EVT_DESC
OBJ_POSITION / HORAS_TMPL / HORAS_SUST / TOTAL_HORAS
156-EBM01 0 0 0
156-EBM01 0 0 0
156-EBM01 0 0 0
156-EBM02 0 0 0
156-EBM02 0 0 0
156-EBM03 0 0 0
156-EBM04 0 0 0
156-EBM04 8 0 8
156-EBM04 0.5 0 0.5
156-EBM04 0.75 0 0.75
156-EBM04 0 1.5 1.5
156-EBM05 0 0 0
156-EBM05 0 0 0
156-EBM05 0 0 0
The information is correct, but I only want one row per OBJ_Position, doing the sum of it's numbers (ACT_EST), like this:
OBJ_POSITION / HORAS_TMPL / HORAS_SUST / TOTAL_HORAS
156-EBM01 0 0 0
156-EBM02 0 0 0
156-EBM03 0 0 0
156-EBM04 9.25 1.5 10.75
156-EBM05 0 0 0
I've tried a lots of group by but none seems to work.
I think removing EVT_JOBTYPE from group by may work, but then it throws an error because its not an aggregate funcion. Same with EVT_DESC...
